how to close logs when use Prophet?

[liangzulin]

when use fit and predict function of prophet, the message like the following will be printed in screen:

STAN OPTIMIZATION COMMAND (LBFGS)

save_iterations = 1
init_alpha = 0.001
tol_obj = 1e-012
tol_grad = 1e-008

tol_rel_obj = 10000

Optimization terminated normally: 
  Convergence detected: absolute parameter change was below tolerance

if I don't want those appear in screen, how to close it?

This output is coming from Stan - see #170 for this same issue. We need an upstream fix. If you are in Python, then #223 describes a decorator you can use to suppress all of the output.

Closing this since it is covered by the other issues.
