Parsing support of shorthand arguments

[kanej]

The argument parser at the cli will need to be enhanced to support shorthand arguments e.g. -f, -fdx

This will require a short design phase and then implementation. Our goal here is to support the -v and -vvvv style parameters that users expect from Foundry.

TODO

• [ ] support for groups of flags e.g. -fdx
• [ ] support for -vvvv, where the number of vs is passed along
