SF Lennard-Jones was added for everyones' enjoyment.  The behavior is tethered to the electrostaticSummationMethod keyword.

converted samples over to the OOPSE-4 file format

Fixed an MPI bug in thermodynamic integration

MPI thermodynamic integration works now.

Adding single precision capabilities to c++ side

rewrite Globals

added some samples

Oops...  MPI now builds...

fixing restraints

moved Package variable into subdirectory makefiles to speed up
the building process

working towards parallel restraints

made the file reading in restraints more intelligent - no longer gives uninformative seg faults
