Case Insensivity of commands, options and parameters

[nagkumar]

It would be good support case in sensitivity of commands..(annotation attribute controlled, with ignoreCase as true)

@CommandLine.Command(name = 'Status')

this way CLI parser should recognize even status, sTatus etc..

Good idea, and is related to #9 and #14. I hadn't thought of also making commands case-insensitive in addition to options.

However I'm not sure that this should be an annotation: note that other attributes for controlling how picocli should do parsing have getter and setter methods on CommandLine. For example, setOverwrittenOptionsAllowed and setUnmatchedArgumentsAllowed. So it would be more consistent to add is/setCaseSensitive methods.

+1, setCaseSensitive method on CommandLine would be my preferred solution.

Fixed in #9; this will be available from picocli 4.3.
