Default values modified by Chris DeGreef

The --default parameter will load up the argument when the user does not specify the argument on the command-line.

This example will run MyProgram with the value "IBM" for --ticker.

CmdLine.create("--type string --key ticker --default IBM");

> MyProgram

Notice the short names used for most of the parameters.

If you specify --multiple as a parameter then the default can be more than one value. This example would load the --ticker argument with "IBM" and "GOOG".

CmdLine.create("-t string -k ticker -m 1 10 --default IBM GOOG");

> MyProgram

If the user enters a value for --ticker then the defaults are not applied at all. In this example the --ticker argument would be loaded with "MSFT" only.

CmdLine.create("-t string -k ticker -m 1 10 --default IBM GOOG");

> MyProgram --ticker MSFT
