0. Changed generated code structure to add matrix creation and
multiplication in just one function. Easier to generate driver code,
might change this later on.
1. Added a "generateDriver" function in DenseMatrixOpsExp. This probably
works only for one example now, but improvements will follow.
2. Added a "Timer" function in cpphelperFuncs.h, referenced in the
generated driver code.
3. Makefile updated - gross hack still exists.
