Added documentation to framework.

Added descriptions for framework classes.
Developing framework in top-down design

Working mainly on initial run phase of the application with configuration
loading and initializing the controller.  Will be working on various classes
when the bootstrap is working.
Tree-based router working

Tree-based router using nested arrays works for basic purposes.  Testing
needs to be done for complex routes.
Working on framework

Placing "COMPLETE" comment note on the top of each framework file as it
is complete and functional -- changes may be made later but all required
methods are defined.
Developing six remaining classes

Need to develop Base\IO\Zip, DbModel, View, HTML, Form, and
Base\Render\Template.
