Detailed Description
Base class for all Laxkit objects.
In the constructor, object_id gets assinged a number returned from getUniqueNumber().
Also provides inc_count() and dec_count() for reference counting. Objects are created with a count of 1.

Decrement the count of the data, deleting if count is less than or equal to 0.
If count gets decremented to 0, then do the following. If deleteMe!=NULL, then call that. Then, if defaultDeleteRefCountedFunc!=NULL, then call that. Then call "delete this" when count==0.
Returns the count. If 0 is returned, the item is gone, and should not be accessed any more.

Returns the type of anObject.
Usually, this corresponds to the C++ class name. However, it is also intended to be used to say what the object should be considered to be. For instance, if you subclass ImagePatchInterface to behave better, the program should still think of it as an ImagePatchInterface, which is something the C++ typeinfo features are not really designed for.

The reference count of the object.
Controlled with inc_count() and dec_count(). When the count is less or equal to 0, then deleteMe is called. See dec_count() for more.
