Error message needed for python interface

Problem

When running the svZeroDSolver from the python interface, using pysvzerod.smulate(), if for some reason the solution is unsuccessful the program will exit with no error message. This is inconvenient as no information is given regarding why the solution was unsuccessful. This is particularly hindering during optimizations, when certain parameters in the config file are being adjusted and may result in an unsuccessful solve. In this case it is inconvenient that the program exits, instead of allowing for future simulations with a different set of parameters.

Solution

To address this, an error message should be added which prints the status of the solution and the reason for the unsuccessful solve.
