find_MAP does nothing?

[Gabriel-p]

I'm testing the find_MAP() method but it does not seem to be doing anything. I.e, it just returns the same input I give it:

> smp.find_MAP(logp, {'met': .015, 'age': 9., 'ext': 0., 'dist': 13., 'mass': 5000.,'binar': .3}, verbose=True, bounds=bounds)
      fun: 5950.001300620037
 hess_inv: <6x6 LbfgsInvHessProduct with dtype=float64>
      jac: array([0., 0., 0., 0., 0., 0.])
  message: b'CONVERGENCE: NORM_OF_PROJECTED_GRADIENT_<=_PGTOL'
     nfev: 1
      nit: 0
   status: 0
  success: True
        x: array([1.5e-02, 9.0e+00, 0.0e+00, 1.3e+01, 5.0e+03, 3.0e-01])
State([('met', array(0.015)), ('age', array(9.)), ('ext', array(0.)), ('dist', array(13.)), ('mass', array(5000.)), ('binar', array(0.3))])

and I can easily find a better solution (only changed the second parameter):

> logp(1.5e-02, 9.5e+00, 0.0e+00, 1.3e+01, 5.0e+03, 3.0e-01)
