calculateLayerDepthForChild() public method

gets the layerDepth for a child composite. It calculates it by first getting the composite (parent) layerDepth the standard way (via zIndexMin/Max) and then subtracting the inverse of the child (O2DMainItem) layerDepth which uses zIndexMaxChild. For this to work intelligently zIndexMaxComp should be the standard scene.zIndexMax value and zIndexMaxChild should be a much higher number. The reason for this is so that the parent component has a small offset to use for each child and so they dont overflow to the next zIndex. Example: parent is 14. Any children must end up being between 14 and 15 so they dont overflow on top of another composite.
