Documentation

A class for a rich light property. The difference between a rich property and a normal on is that the rich property may either be "explicit" in which case the data for the property is stored locally, or "named" in which case the data for the property is stored in a global object. The idea is that when the global object is modified, then so are all of the objects which point at that table.
