Stochasticity in function block

Relevant to previously discussed topic with @Dashadower which he might have mentioned could be done with C++ coding.

Random number generators are only allowed in transformed data block, generated quantities block or user-defined functions with names ending in _rng.

This is resolved by feeding randomly generated data (via stan data block).
