Modified noKernelMultiGilStat to handle no skips
Changed noKernelMultiGilStat to handle cases w/o skips. Pass haveBlocks = FALSE or blockIndex = NULL in this case. Need to debug more thoroughly to make sure everything works as expected. C code also changed in case of noblocks to compute only general semivariance statistics. Reorganized and made copies of old code in oldFiles.
