+function doDrawCellOutlinePAW( data, channel, ids1, ids2)
+% Description : 
+%
+% Opens fig with outlines of cells drawn. The script currently allows
+% you to input two sets of cell IDs to be colored in blue (ids1) and red
+% (ids2). Currently any cells with IDs not listed in ids1 or ids2 will be
+% outlined in yellow. This is all customizable. If you wish to
+% change the colors, replace 'b' etc with the color of your choice. If you
+% do not want cells whose IDs are missing from the ID lists to be outlined, 
+% remove code in 'else' block. If you wish to send in additional id lists,
+% add ids3, etc to the line above, and ammend the if/else block.
+%
+% List of inputs:
+%
+% data: A loaded err.mat file for the image you want outlines drawn on
+% channel: The channel to draw outline on (1-phase, 2-fluor1)
+% ids1: IDs of cells you want outlined in one color (default: blue)
+% ids2: IDs of cells you want outlined in a second color (default: red)
