custom types

[danielburrell]

Allow users to point to custom types like
uk.co.solong.rest2java.custom.BooleanNumber
a class that tells the controller to accept boolean but provide 1,0 as output
Another example:
uk.co.solong.rest2java.custom.BooleanYes
a class that tells the controller to accept boolean but provide yes,no as output
These can all be helper useful classes, like array to csv
but more generally make the code generic so that it accepts constructor types with tostring
where you promise to provide your own class that accepts a value as a constructor and a string as output. (maybe pass in to constructor regardless rather than just doing toString)
provide override method to call instead of tostring instead. (0-arity)
