Detailed Description

adds some convenience methods for standard meta data attached to a graphic object.

adds some convenience methods for standard meta data attached to a graphic object. By default the metadata is just an uncomitted id, but using this sets it to be a mutable dictionary. You can then easily get and set values in that dictionary.
