trying to get rasters!

making progress. now getting "cannot display grey area" error from
rdd_rasters. beware of files assuming that the basecode is the second
code dropped.
changed axes on GUI
got rid of myBreakpoints
Merge branch 'integrate-2AFC-task'
automate basecode detection

allows proper basecode detection for tasks regardless of when basecode
is dropped by REX
allow for 'trigger' channels with other names

can now replace trigger channels of a known name with 'trigger'
Merge branch 'integrate-2AFC-task'
