Add typing support

Descriptor decorator implementing a class-level, read-only
|
||
property, which caches its results on the class(es) on which it
|
||
operates.
|
||
Inheritance is supported, insofar as the descriptor is never hidden
|
||
by its cache; rather, it stores values under its access name with
|
||
added underscores. For example, when wrapping getters named
|
||
"choices", "choices_" or "_choices", each class's result is stored
|
||
on the class at "_choices_"; decoration of a getter named
|
||
"_choices_" would raise an exception.
