A rudimentary oommfdecoder command line

Includes a sample omf file.
Add copyright, licence and def main()
Add basic argparse commands. Create decoder.py

decoder.py contains functions needed by oommfdecoder.py
Add catch for incorrect file types
Add batch runner thing.
Comment out pickle command.

It was over-writing the matlab output so that I could not open the
output file in output.

A planned feature must be to select between pickle and matlab output.
Add commented out line ready for pickle options.
Add output filetype selector
Remove batch decoder debug lines.
Remove show headers option. Add text alerts.
Add  comment to explain filetype catch.
Create Readme.txt
