 *
 * ### 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.

 *

 * - `required` - Set to true to force this option to be required.  An exception will be thrown
 *    when this option is not present.
 * - `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.
 * 
 * @param string $name The name you want to the value to be parsed out as when options are parsed.
 * @param array $params An array of parameters that define the behavior of the option
 * @return ConsoleOptionParser returns $this.
