Fixed seg fault in serial and sm versions
Fixed error that particles were not moving (grid not loaded)
Split ParticleCtls across GridCtls in shared memory case
Fixed bilinear interpolation
Converted all doubles to reals ('typedef double real' or 'typedef float real' when compiling) and serialized PGroup and ParticleVec pointers. Note that this commit introduces a memory leak in cuda_ptm that needs to be fixed"
Added pointer serialization to Grid and Frame and fixed seg fault in CUDAPTM
CUDA version is working!!! and needs to be cleaned up :(
Updataed CUDA version to use bilinear interpolation
