ROIs now have colors which correspond to label #1

ROIs now have colors which correspond to their label. Converting to
patch objects seems unnecessary, as this accomplishes everything
necessary.
Added doc for multiple arg init func

Added documentation for initialization functions with multiple
arguments.
Merge remote-tracking branch 'origin/master' into ari
Added func to change paths in acqObj to local

Added function changeAcqPathToLocal which changes the paths to the
binary movie, and the covFile to local paths.
Sped up createAcqObjects

CreateAcquisitionObjects now checks for a txt file before loading in the
acqObject and writes a text file if an acqObject is complete. This
prevents having to load in every acqObject on every run.

Added check to am2PInit to return if no movies.
Updated to use patch objects #1

Updated MJLMSelectROIs to use patch objects in lieu of the rgb color
scheme. Images are now displayed using imagesc and are now grayscale
(one-dimensional).
MJLMSelectROIs now saves hasBeenViewed

MJLMSelectROIs now saves hasBeenViewed as a field of obj.roInfo so that
it persists across instances of selectROIs.
Improved speed of patch objects #1

Improved the speed of patch object plotting by making it not replot
every time. If roi deleted, replots everything.

Also fixed bug in saving hasBeenViewed to obj.roiInfo.
