Code framework down.

Most of the framework is down and functional. At this point we have the major
libraries linking:

   1. MPI
   2. FFTW
   3. HDF5

Next we need to get all of the working arrays allocated properly and test the 2D
FFTs with some sample signals. After that, we need to:

   1. Build the RHS of the ODEs using spectral means for spatial derivatives.
   2. Code the time integrator.
