CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the priority of U.S. provisional patent application 60/647,936, filed Jan. 31, 2005, which is incorporated herein by reference. BRIEF SUMMARY OF THE INVENTION [0002] This invention relates to a wick sheet used in combination with a wick movement limiting structure embedded in a wax candle. The wick sheet when ignited makes sustainable horizontal flames along the lateral line(s) of the exposed wick on the surface of a wax candle. The wick sheet can be arranged in an unlimited variety of configurations providing heat, light and viewing entertainment to the user. BACKGROUND OF THE INVENTION [0003] Most outdoor candles, such as the popular citronella candle device sold in department stores, similar to, for instance, the candle of U.S. Pat. No. 3,285,694 to Marchi, comprise a bucket, typically containing paraffin wax scented with citronella oil and employing one to three round cord or string-like wicks. The flame from this type of device burns only in a localized area around the string-like wick(s) providing relatively low amounts of heat and light and does not spread laterally across the candle surface. The appearance of the simple flame(s) from such devices is boring compared to the flame from, for instance, a wood fire, which some outdoorsmen refer to as "cowboy TV". [0004] One way of achieving a more complex, interesting candle with greater heat and light output is through a wick sheet instead of a string-like wick. Although rectangular shaped wick sheets have been used extensively in oil lamp systems, both in straight sheets and in the form of a tube, such as those shown in U.S. Pat. Nos. 4,720,260 and 4,836,773 to Yamaguchi, few if any have been utilized in wax-based candles. Nor have they been provided with wick support structures that limit the movement of the wick sheet, while self-adjusting to the level of the fuel, as is necessary for operation in a wax based system. This is especially true of these oil based systems, which typically utilize manual wick sheet adjustment, usually through a mechanical control, to adjust the flame and wick height in the system and, therefore, need an adjustable, limited wick system without the support aspects typically used in a wax system. Thus, this type of system does not perform well in a solid wax medium. In addition the mechanism protrudes above the oil surface, which is unattractive in a wax based system. [0005] Additionally, the wicks in these oil burning systems are typically produced by knitting a band of wick cloth having at least a burner part that is made of non-combustible textile material. This limits the wick sheet in many ways, as the sheets must be thicker and will generally burn hotter. Thus the oil burning wick sheet fabrics described in these systems are thicker, do not completely burn, and would burn dangerously hot if applied in a wax fuel composition producing flare ups, where the entire wax surface may ignite, which is not only hazardous, but also consumes wax at such a rate as to render a wax candle with such a thick wick economically undesirable to the average consumer. [0006] Attempts have been made to provide portable burners. However, none of these have provided satisfactory controllable burning systems of wax candle systems. They are generally directed to portable fire systems that burn quickly and across there entire surface to ignite a fire similar that provided by a sterno can. One such device is provided in U.S. Pat. No. 3,367,758 to Ambrose, et al. The Ambrose device provides for a burner with wax and a burnable container. The device shown is designed to create an uncontrolled conflagration across the entire surface of the wax, consuming both the wax and the container. To this end, the design does not provide for a wick sheet nor does it provide for a wick sheet support structure. Specifically, a wick sheet or wick sheet support structure that would provide for a controlled, area specific burn and prevent the conflagration across the entire surface of the system, as controlling the wick level or position as the burning composition is consumed is unimportant in this type of design. [0007] Additionally, there are numerous portable devices and fuel compositions which are designed to provide a convenient fire without the problem of gathering wood or other fuel and continuously feeding it to the fire. For instance, the ready to use campfire shown in U.S. Pat. No. 5,967,769 to Thompson, comprising woodchips embedded in a mineral spirits and paraffin wax mixture, and includes an unsupported paper spiral-shaped wick. However, this type of flame smells of chemicals, burns quickly and with a significantly higher flame than any similar wax candle. Additionally, the paper wick sheets provided are prone to burning or setting alight substantially the entire surface of the device, leading to an uncontrolled burn that consumes the fuel at a maximum rate. Further, the wicks provided are not supported or retained, allowing for movement of the wick material as the combustible material is quickly consumed None of these instant campfire type devices utilizes significant wick support structures. [0008] Further, although wick tabs employed in this wick sheet and wick sheet support system invention have been utilized in previous single, string-like wick devices, none have been provided in a wax based wick sheet system. For instance, a wick support base is provided in U.S. Pat. No. 1,344,446 to Engman. However, the device of Engman holds a string-like wick to the bottom of a candle; this limits the candle to the single, string-like wick. Moreover, these string-like wick anchors do not incorporate wick support structures or posts. [0009] There exists a need to provide a portable heat and light source that provides a controllable and entertaining flame that issues from a wick sheet that is securely held within a fuel composition. SUMMARY OF THE INVENTION [0010] An object of the instant invention is to provide a novel wick sheet and wick sheet support structure in combination with a fire resistant portable wax filled container. [0011] In another aspect, the present invention's wick sheet fabric and supporting posts can be arranged in unlimited shapes and designs to create unlimited flame configurations along the surface of the wax composition once assembled and lit. [0012] In still another aspect, the present invention comprises a unique wick movement-limiting structure which holds a wick sheet upright in a solid or liquid fuel composition. [0013] A further object of the present invention to provide a candle device which provides a greater amount of light, heat and "flame entertainment" than a typical outdoor citronella candle. [0014] Another object of the present invention is to provide an outdoor candle, or fireplace candle, which is safely contained, readily extinguishable, and does not emit dangerous sparks, while still providing the desirable heat and flame entertainment of a campfire. [0015] A still further object of the invention is to utilize an at least one wick tab to hold a solid support post to the bottom of a candle in conjunction with a wick sheet. [0016] In still another aspect, the present invention is a new combination of ingredients, including in an exemplary application a soy based, cleaner burning wax in combination with a wooden wick sheet support structure and a principally cotton based wick sheet to provide a novel, portable, ready-to-use candle. [0017] Yet a further object of the invention is to provide a wick sheet with wick material that can be both fully flammable or incorporate both a flammable and a non-combustible composition. [0018] The apparatus of the invention includes a portable apparatus producing a sustainable horizontal flame along the line of an at least one wick sheet, having a heat and flame resistant container that has an upwardly facing open mouth, a fuel absorbent at least one wick sheet and wick sheet support structure disposed within the container and retaining the wick sheet within said container, and a combustible composition filling the container and substantially saturating the wick sheet such that the wick sheet is substantially embedded in the combustible composition. [0019] The container can be a removable container. For instance the removable container can be a mold, like a candle mold or other portable flame producing apparatus mold. The at least one wick sheet and the wick sheet support structure and the combustible composition can be made removable from the mold. The combustible composition cane be at least one of a wax, an oil, and a gel. The combustible composition can be, in one exemplary embodiment, a vegetable based composition. [0020] The at least one wick sheet and wick sheet support structure can support the sustainable flame along a localized area of the combustible composition running along an exposed portion of the wick sheet. The at least one wick sheet can also be rectangular and the fuel composition can be poured in the container so that the rectangular wick sheet fabric is embedded in the fuel composition and disposed vertically, extending substantially from the bottom of said container to above the surface of the fuel composition nearest the open end of the container such that the portion of the at least one wick sheet that supports the sustainable flame along a localized area of the combustible composition is protruding above the surface.
