+Defines a grid in the XZ space with predefined cell size in each direction. Each cell then receives exactly
+one structure (provided by the descendant class). The structure is placed within the cell, but doesn't need
+to be bounded by the cell, it can be well outside the cell; the generator uses the MaxStructureSize parameter
+to determine how far away from the cell the structure can be at most.
+This class provides a cache for the structures generated for successive chunks and manages that cache. It
+also provides the cFinishGen override that uses the cache to actually generate the structure into chunk data.
+
+After generating each chunk the cache is checked for size, each item in the cache has a cost associated with
+it and the cache is trimmed (from its least-recently-used end) so that the sum of the cost in the cache is
+less than m_MaxCacheSize
+
+To use this class, declare a descendant class that implements the overridable methods, then create an
+instance of that class. The descendant must provide the CreateStructure() function that is called to generate
+a structure at the specific grid cell.
+
+The descendant must use a specific cStructure descendant to provide the actual structure that gets generated.
+The structure must provide the DrawIntoChunk() function that generates the structure into the chunk data, and
+can override the GetCacheCost() function that returns the cost of that structure in the cache.
