kerrbb model

Jeff McClintock writes :

Some users of kerrbb have been freezing the inclination (par3), the mass(par4), and the distance (par6) and then allowing the normalization constant K to vary. This is not correct: with i, M and D fixed, the normalization should be frozen at K = 1. The current instructions for running kerrbb, which we provided to you, are not clear on this point. When it is convenient, please change the last line of the description of kerrbb to read something like the following:

K =normalization. Should be set to 1 if the inclination, mass and distance are frozen.

We have made this change in the v11 and v12 documentation.
