Added documentation line to StosBrute
Remove unused import for scipy.misc.imsave
CreateVikingXML was requiring volume parameters such as StosMap but the lab often uses Viking for plain mosaics without a volume.  Removed requirement.
IDOC test builds downsampled by 8 images instead of downsampled by 1.  Test goes faster and the PMG test has downsampled by 1 covered already.
New
===

* SetPruneCutoff pipeline to save users from editting volumedata.xml files deep in volume
* SetContrast pipeline to save users from editting volumedata.xml files deep in volume
* CreateVikingXML calls added to TEMBuild and TEMAlign scripts
* Add version history documentation

Fixes
=====

* CreateVikingXML no longer requires volume related parameters.  Allows unregistered mosaic sets to be published to Viking.
* Histogram image updates if contrast parameters editted
Histogram images update to reflect the current autolevelhint settings
Fixed Contrast filter referenced in .cmd files for TEM and CMP
