pilotAnalysis2.m:

Added new input option: 'redo', n. This option lets the program redo only
a single trial, which is handy in case a mistake is made during the
first-pass analysis of the data. Note that this option can be used only
after the first-pass analysis has finished and the resultant mat file has
been saved.

Usage example:
pilotAnalysis2('fmrig', 3, 'SEQ03C01_behavioral', 'test7', 3, 'scai',
'noFilter', 'redo', 17)

'redo' must be followed by a trial number.
