Rename of Generators to Geometry, and Base to Utilities
Update of files to match changed folder names.   My run_script works, but I may have missed something of course.
Removal of declare/new, set and get pore&throat property methods in anticipation of the new self-protecting dictionary class
 Removed the declare_property calls in the GenericNetwork init since the methods were deleted.  The code does not break, so it seems there were not really needd.
Test script that demonstrate the failure to import OpenPNM in the test folder.
Small changes to GenericNetwork methods (including an undelete of get_num_pores)
Renames GenericGenerator to GenericGeometry to in keeping with changing module name to Geometry.  Tried to change code in all necessary places, but please check for yourselves.
Added to 'geometry altering' functions to GenericGeometry.  These don't work because of the way network objects are passed around.  I have filed a bug, and added a test script.
