ENH: Adding template building
ENH: Added longitudinal Freesurfer processing
Merge pull request #167 from dmwelch/FSNipype

ENH: Added longitudinal Freesurfer processing
Merge pull request #168 from aghayoor/SphericalGenerationModuleForBRAINSCut

Add the spherical coordinate generation to the BRAINSCut
Merge pull request #166 from reginakim/DataSink_STAPLE

DEV: Add DataSink for STAPLE
COMP: use 17 digits of precision writing out doubles as text
Merge pull request #169 from Chaircrusher/DWIConvert_NRRD_Precision_Fix

Dwi convert nrrd precision fix
BUG: Fixing variable naming to match WorkupT1T2.py
ENH: Removed white matter probability file from input to fsscript.py
STYLE: Updated input traits subcommand help string
ENH: Integrated Freesurfer cross-sectional template building and longitudinal workups to Autoworkup
Merge pull request #170 from dmwelch/enh/fsLongitudinal

ENH: Integrated FS Longitudinal into Autoworkup
ENH: Fix to include consistent naming of FreeSurfer spelling.
BUG:  This version of the freesurfer wrapping still has errors.

Working on a solution over the next few days.
BUG: Fixed indentation and node connections for FS template workflow
BUG: Fixed pipeline for Freesurfer longitudinal processing
BUG: Remove use of https for svn repository.

The https protocol from nitrc requires that credentials be configured.  This
makes general checkouts difficult.  Using http makes the process more
robust.
Change1: new spherical coordinate definition in BRAINSCut

The previous formula were not correct, so they are modified based on
considerations on symmetric property of brain.
This is the first commit out of three:
As a short comment, here we have:
phi = arctan( |y|/x )
theta = arctan( |y|/z )
