Purpose:Abstract class to use as a basis for building WebSpeed for
PASOE request handlers
Author(s):mbanks
Created:Wed Jan 14 14:38:25 EST 2015
Notes:* Concrete child classes must implement the HandleNotImplemented and
HandleNotAllowedMethod methods so which are the baseline on
we control the messages back (either created entirely in ABL or
served by PASOE).
to control the way error states are handled. The default is to return
an integer status code.
