Subject: ENH, MAINT: Use an abstract base class for the polynomial classes.

The new base is ABCPolyBase and is intended to replace the use of the
polytemplate string.  In this way the need to compile the polynomial
classes on import is avoided.

Closes #634. Closes #3639.

Subject: DOC: Fixup documentation for new way of generating classes.

Move the class documentation to the place of definition in the
appropriate module. This allow for documenting the specific series kind
along with the series specific default domains and windows

Remove template placeholders from the ABCPolyBase class documention.

General fixup of documentation that rendered poorly.
