Allow to specify a list of valid values to an option.

[jarrodhroberson]

for example:

@Option(shortName = "f", longName = "format", defaultValue = "csv", validValues = "csv,json,xml", description = "Output File Format")
public Set<String> getFormats();

If it also auto generated an addition to the description like "Output File Format defaultValue=csv valid=[csv,json,xml]" it would go a long way to adding more information with no effort.

I wonder if a set of an enum would work. Or if it doesn't that might be the
way to implement it cleaner. Certainly would accept a patch adding this
feature, or I will look at it when I get time.

I will add this but I gave a cursory look at it and all the indirection made it hard to see where to begin.

Umm, yes I can understand that. I am slowly refactoring it to allow all the
different parts to be swapped out so that people can plug in their own
parser, validator, etc, but its not finished yet and its not documented how
to do it. ArgumentPresenterImpl is what you want, the main loop is in the
presentArguments method it calls out to all the other parts.
