required checking

• Allow String arguments, which are required
• more meaningful error messages
• long name is always defined, unless SuppressLongName is present
• printUsage method handles OtherTokens and EverythingAfter more correctly
• printUsage method mentions all possible forms of every argument
• removed the ArgumentName annotation, added an argumentName argument to Description instead

auto long name

• Long name is defined by default, unless @SuppressLongName is present.
• Add javadoc for every annotation.

Annotated abstract class

Breaking change: Move away from annotated constructor / static method. Use an annotated abstract class instead, similar to auto-value.
