throw exceptions up the call stack and handle exception reporting/serialization centrally in the handle() method

use logging, not system.out

consolidate session management and parameter preparation in the superclass

throw exceptions up the call stack rather than catching and handling them differently for each possible rest path

consolidate multi part handling in the super class - subclasses need only call the appropriate helper to get access to the needed resources. superclass does some validation to make sure the files are in place in the request

cleaning up the handlers -- removing superclass methods.

refactor to use D1RestServlet and D1ResourceHandler for the D1 rest interface

deprecate the old rest servlet in favor of the new D1-specific (CN/MN) versions

MN rest servlet, handler and mappings

share getSystemMetadata (before refactoring the superclass)
