new(*arguments) public

Set up option processing.

The options to support are passed to new() as an array of arrays. Each sub-array contains any number of String option names which carry the same meaning, and one of the following flags:

GetoptLong::NO_ARGUMENT :Option does not take an argument.
GetoptLong::REQUIRED_ARGUMENT :Option always takes an argument.
GetoptLong::OPTIONAL_ARGUMENT :Option may or may not take an argument.

The first option name is considered to be the preferred (canonical) name. Other than that, the elements of each sub-array can be in any order.
