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.
NF: Add a visualization for FS data.
DOC: More documentation for the pysurfer function.
Merge branch 'restore_fixes' of https://github.com/arokem/vistasoft
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

updated display of Session variables to account for nifti structs in inplane rather than old anat.mat form of inplane
updates to fix within scan motion compensation code. note that this new code was tested with the vistatest validation function test_withinScansMotionComp as well as the whole BOLD suite tested with mrvTest
