Reorganizing KTCore a bit to make it more inclusive of the things that need to be there.
Remade the main Katydid CMakeLists file to use the new Katydid.cmake file.
Added KTCore/Templates, including the processor template, and the main CMakeLists template.
More reorganization
Moved KTReader and KTWriter to KTCore
Added Katydid Core version variables
Other minor updates
Create a MATLAB_LIBRARY_DIR variable in the main CMakeLists file.
