The last missing piece is now committed - the JSON-RPC interface is now self-documenting via an automatically
generated JSON Schema that lists all RPC methods with their parameters and return values. This documentation
schema is created from simple to use documentation code in each rpc server function, see mjsonrpc.cxx.

To kick the tires, checkout the feature/json_rpc branch, build mhttpd, setup the examples/javascript1 experiment,
run mhttpd in the terminal, from the "status" page, go to the "example" custom page, press "push me" in the mjsonrpc_db_get_values() section,
mhttpd will print the schema file on the terminal. Use any json schema visualization tool to look at it. In the future I hope
to link this schema to the midas "help" page.

(there is also an interesting discussion on why there is no RFC for JSON schema - the draft expired several years ago)
