Create lib directory in FSLDEVDIR for libbedpostx_cuda.so if it doesn't exists and copy there after compile in local directory

Join MCMC kernels (simplify code), avoid Static Declaration of arrays (moved to shared or Global Memory) and reduce precision in some structures (double to float)

Delete unnecessary params in Samples Record-Save. Write output in runmcmc_record_kernel (maybe iterations)

Pass some parameters to FIT instead of read from options to do it more general and use it in RUBIX. Delete unnecessary params in Samples Save
