FIELD OF THE INVENTION [0001] The present invention relates to a lightweight panel for use as an outer layer of a dwelling wall and a dwelling wall constructed using such lightweight panels. BACKGROUND [0002] Many conventional dwellings have brick veneer walls that typically comprise a structural frame having an outer layer of bricks and an inner layer of plasterboard liner. In recent years such walls have been constructed with insulation foil disposed therein. The use of the insulation foil increases the thermal resistance of the dwelling wall and results in a far more energy efficient home. Whilst many home builders and the general public at large are becoming more aware of the advantages of energy efficient homes, their cost of construction are still quite considerable, particularly due to the labour and materials handling required. [0003] The brick veneer is a form of cladding which covers the load bearing wall and generally provides an aesthetically pleasing exterior finish. Because of thermal expansion and contraction (and indeed even expansion of bricks with age) about every 50 feet (15 meters) in a brick veneer wall it is necessary to provide a control joint. This is a vertical gap in the bricks up to 15 mm in width which is filled with a compressible sealing material. Between the bricks themselves is a layer of mortar which bonds to the bricks and thus binds all the bricks together. The cost of conventionally laid bricks is relatively high because of the need for skilled (and therefore highly paid) bricklayers and the need for mortar with its inherent delays involved in mixing, laying and subsequent clean up. [0004] The genesis of the present invention is a desire to provide a lightweight panel that can be used in the construction of a dwelling wall that has a thermal resistance greater than that of a brick veneer wall, and is relatively simple to construct. SUMMARY OF INVENTION [0005] According to a first aspect the present invention there is disclosed a cladding and insulating veneer arrangement fixed to a load bearing subwall, said arrangement comprising a vertically and horizontally extending stack of substantially vertically aligned panels which are loose fixed without bonding jointing material between the panels, and retaining clips extending between said panels and the subwall. [0006] According to a second aspect the present invention there is disclosed a method of erecting a cladding and insulating veneer arrangement for a load bearing subwall, said method comprising the steps of: (i) positioning a plurality of substantially vertically aligned panels in edge abutment to form a row, (ii) loose fixing said panels without bonding jointing material between the panels, (iii) utilizing retaining clips extending between said panels and said subwall to retain said panels in said row, and (iv) repeating step (i) for a vertically adjacent row. [0007] According to a third aspect the present invention there is disclosed a lightweight panel for use in the abovementioned cladding and insulating arrangement, said panel being formed substantially from concrete which comprises cement, sand, lightweight aggregate, superplasticiser and water; having a density in the range of 500-1500 kg/m.sup.3; and having an inter-engagement means to enable said panel to be loose fixed with a plurality of like panels in a vertically and horizontally extending stack of said panels, and said inter-engagement means being shaped to permit engagement with a retaining clip which permits said stack of panels to be retained adjacent a subwall from which said retaining clip extends. BRIEF DESCRIPTION OF THE DRAWINGS [0008] FIG. 1 is a perspective cut-away corner view of a first embodiment of a dwelling wall in accordance with the present invention. [0009] FIG. 2 is a horizontal cross-sectional view of the dwelling wall shown in FIG. 1. [0010] FIG. 3 is a perspective view of a standard lightweight concrete panel used in the construction of the dwelling wall shown in FIG. 1; [0011] FIGS. 4a and 4b depict perspective views of corner lightweight concrete panels used in the construction of the dwelling wall shown in FIG. 1; [0012] FIG. 5 is a perspective view of a first embodiment of a panel clip used in the construction of the dwelling wall shown in FIG. 1, [0013] FIG. 6 is a perspective view of a wall in accordance with a second embodiment, and [0014] FIG. 7 is a horizontal cross-sectional view through adjoining panels of a third embodiment. MODE OF CARRYING OUT INVENTION [0015] FIGS. 1 and 2 illustrate, in a simplified schematic fashion, the construction of a dwelling wall 1 having a structural frame comprising of wooden studs 2 and noggings 3. In this embodiment the studs 2 and noggings 3 are preferably 100 mm.times.50 mm (4.times.2 inches) pine, but in other embodiments may be of different size, timber or material.
