First commit after overwriting GaborRFMap from MaunsellLab/Lablib-plugins as of 23/9/13, just before upgrading to Xcode 5
Merge branch 'MaunsellLab'
Merging from MaunsellLab - changes to make the final code as similar to MaunsellLab as possible
Fixed a couple of bugs introduced by the merge. As of now, GaborRFMap works with a single stimulus, but gives computer errors when multiple stimuli are presented
