Patch for Hoda Amer.

- The core patch modifies the CModelBuilder to recognize pointers to functions. 
- The tests patch changes the CModelElementsTests and puts the pointer to function test back in its original place (as a variable). 
- The ui patch modifies the NewClassWizard to use search in finding a base class ( the new indexer must be on for it to work ).
