Add an endpoint to generate JSON code

[edwardcapriolo]

So we should have an endpoint that is an html form like

drop down : operation
CQLQuery
Set
Get
...

After the first drop we look at the argumentsions in operations.cqlQuery()
and produce another form with n text boxes for the arguments

Then the next post should return the raw json the user needs.

This makes it easy to a json user to figure out what our wire format is.

A forth optional step can submit the query and return the result
