Program sfnormalize | Normalization of data batches up to a given axis.
[SYNOPSIS]
sfnormalize < in.rsf > out.rsf axis=1 type=
[COMMENTS]
Can either normalize to be between [0,1] with type=m
or have mean=0, std dev = 1 with type=s 
[PARAMETERS]
int     | axis | =1 |   | 	normalize so axes groups up to this dimension have mean 0, std deviation 1 
string  | type | = |   | 	'm' means data are biased and scaled to be between 0 and 1 
       's' means data are biased and scaled to have mean=0, std dev = 1
