Support for Map Interface in CXF Parameter Beans

Apache CXF Rest Services doesn't support java.util.Map interface as their service arguments. They even do not support java.util.Map interface inside a bean.

This fix is to support Map interface as arguments and fields inside a bean.

> The code is tested with sample services like,
> public String debug(@FormParam("")TestEmployeeTO testObject1,@FormParam("map") Map<String,Integer> map)
>
> public class TestEmployeeTO

{ > > private HashMap<String,String> currencies; > > //getters/setters > }

> Input Data
> map.x=11&map.y=9&currencies.IND=INR&currencies.USA=DOLLAR
> Output
> TestEmployeeTO[currencies=

{IND=INR, USA=DOLLAR}

]
> map=

{y=9, x=11}
