IStringConverter must NOT be Inner Class #489

This could be corrected with a change to the documentation.

The problem is that the parameter types for an inner class includes the parent class.
https://github.com/cbeust/jcommander/blob/master/src/main/java/com/beust/jcommander/JCommander.java#L1355
This means that the 'ctor' is not set and null is returned for inner class Converters.

It can be an inner class, you just have to declare it as static class
