Adjusted all of the source code to point to the header files in their new
locations. Adjusted the makefiles for the header locations as well.
Added .gitignore files in the test directories to ignore test object code.
Changed the way JITEvents are created and handled. Instead of taking a function pointer directly we save a name of a function to the JITEvent class. The class will dynamically look up a function that matches the name both during event creation and during checkpoint restart.
Fixes#53
