colSums(), colMeans(), rowSums() and rowMeans() for all sparce *gCMatrix()es

Parameters
xa ?gCMatrix, i.e. sparse column-compressed Matrix
NArmlogical indicating if NA's should be remove 'na.rm' in R
spReslogical = 'sparseResult' indicating if result should be sparse
translogical: TRUE <==> row[Sums/Means] <==> compute col*s( t(x) )
meanslogical: TRUE <==> compute [row/col]Means() , not *Sums()
