I initially wrote findInSubdirectory to make it more convenient to pass in data files to python scripts from the command line. Specifically,
# Create parser for command line options
parser = OptionParser()
# Get filename/resolve path
parser.add_option("-f", "--file", dest="filename", type="string",
help="Specifies log file", metavar="FILE")
parser.add_option("-s", "--subdirectory", dest="subdirectory", type="string",
help="Specifies path to logfile", metavar="subdirectory")
subdirectory = options.subdirectory
filename = options.filename
path_to_file = findInSubdirectory(filename, subdirectory)
logData = open(path_to_file, 'r')
