*
* ### Switches
*
* Named arguments come in two forms, long and short. Long arguments are preceeded
* by two - and give a more verbose option name. i.e. `--version`. Short arguments are
* preceeded by one - and are only one character long. They usually match with a long option,
* and provide a more terse alternative.
*
* ### Providing Help text
*
* By providing help text for your positional arguments and named arguments, the ConsoleOptionParser
* can generate a help display for you. You can view the help for shells by using the `--help` or `-h` switch.

* - `description` - Description for this option.
* - `type` - Require a certain type. Available types are `int` and `string`. If the options
* value is the wrong type an exception will be raised.
* - `default` - The default value for this option. If not defined the default will be null.
