#============================================================
#  Author:   John Theofanopoulos
#  A simple parser.   Takes the output files generated during the build process and
# extracts information relating to the tests.  
#
#  Notes:
#    To capture an output file under VS builds use the following:
#      devenv [build instructions]  > Output.txt & type Output.txt
# 
#    To capture an output file under GCC/Linux builds use the following:
#      make | tee Output.txt
#
#    To use this parser use the following command
#    ruby parseOutput.rb [options] [file]
#        options:  -xml  : produce a JUnit compatible XML file
#        file      :  file to scan for results
