BF: Residuals need to be considered both above and below.

Also, lsqnonlin seems to perform better than fminsearch in recovering the true
tensor parameters: https://gist.github.com/arokem/990983ad77b93f7c0559
BF: Fitting after outlier-exclusion should not use sigma weighting.
Mean-normalize the GMM weights.
NF: Use FS and Benson method to generate retinotopy estimates.
Two things

1. Added documentation
2. Keep only the gzipped version.
RF: keep intermediate files.
moved mrManDist.mexmaci64 to a place matlab can find it, which is where other mrManDist mex functions live
added dictionary item cmapcurrent
updates to correctly get/set numcycles and framesToUse with viewGet viewSet
replaced writeFileNifti with niftiWrite
moved error check for mrv version to prior to opening window
NF: Add a visualization for FS data.
DOC: More documentation for the pysurfer function.
changed pixdim to ensure that it gets all values, not just xyz, in case the nifti data has more than 3 dimensions
Change fprintf message to indicate the mfile from which the message is written
two edits: first, use relative rather than absolute for paths for writing inplane nifti. second, eliminate redundant writeFileNifti. previously, the niftis were being written and then immediately overwritten with no change
when sto fields do not exist, we must write srow_x, srow_y, srow_z to a vector of 4 zeros rather than one zero otherwise niftiWrite fails
