integer arrays should be assignable to real arrays #167

Summary:

I think this should work:

int[3] x = { 1, 2, 3};
real[3] y = x; // FAILS as of Stan 2.17

This is related to #830; it'd be nice to provide full covariance and contravariance through containers for the int to real promotion.

Current Version:

v2.17.0
