The instruction file has the following format.  Line endings and 
white space are important so write instructions with care.
The ID's can be anything, *EXCEPT SPACES*, that can be used as part
of a file name (this is a slight modification from previous versions
which required ints)


Set Name
SetID                         
PromptID1 text of instruction1
PromptID2 text of instruction2
...
PromptIDN text of instructionN


To call the program run:
  > UserCollectionForms path-to-instructions dir-to-save-files-in

The paths are relative to the directory from which the program is called.  The user will
be prompted to enter a name (or id).  The images will then be saved in a sub
directory of the specified output directory.  The sub directory will have the same name
as the user.
