Added VecScatterSetUp() and converted implementations to use it to compute scatter information
Pull "MPI1" and "MPI3" specific code out of common VecScatter impls code This allows future implementations to use the common code also without changing the common code
Seperate VecScatter implementation code into three subdirectories seq, mpi1, and mpi3
