Simplify process of setting under/over colors
Added more robust method for visualizing undershoots/overshoots;  User defined function 'setcolors' is now only called if the user has specified 'UserColorMapping' in setplot2 or setplot3
Added comments on flag 'UserColorMapping'
Added description of flag for visualizing under/over shoots in data
Moved forestclaw flag setting to plotframe2.m
Increased number of possible random colors to choose from
Added description of flag for visualizing under/overshoots in data
Changed underover flag to 'underoverflag', so as not to conflict with 'underover.m' script
Commands in this file will be called at the end of plotframe2 and plotframe3
Allowed for more space in under/overshoot region of colorbar
Changed name to colorbar_underover
Added call to default afterframe file
Fixed documentation to reflect name change to function
Create a frame name based on FRAME and user specified file and extension, e.g.

         framename(3,'spiral0000','png','plots');

creates 'plots/spiral0003.png'.
Added functionality to visualize under/over shoots
Make prompt to run setplotN depend on value of NoQuery
