NameError: name 'ConvergenceError' is not defined

[PhilippHoellmer]

In line 1963 of pymbar/pymbar/mbar.py, the code tries to catch a ConvergenceError that is nowhere defined in that file. Hence, if that part of the code is reached, one gets a NameError.

The simple solution is to import the ConvergenceError from pymbar.utils at the top of the file.

As a related question: At the same place of the code, would it also make sense to catch the pymbar.utils.BoundsError that, as the pymbar.utils.ConvergenceError, can be thrown by the bar function?
