/** Groups a number of TerrainRenderables (tiles) into a page, which is
the unit of loading / unloading.
@remarks
Note that this class, whilst holding onto TerrainRenderable instances,
does not actually process or initialise them itself - this is
intentional so the TerrainPageSource which is providing the tiles
is able to load and prepare each renderable incrementally if required,
thus avoiding any 'single hit' load methods for the page.
@par
All this class does do is pre-create a 2D vector of 'slots' in which
to place the TerrainRenderable pointers, which it does on
construction. Note that this structure is public to allow completely
free access to users of this class.
