How can errors in model loading be retrieved?

[jonrkarr]

japi.lqm.load appears to return None for invalid files at https://github.com/GINsim/GINsim-python/blob/master/biolqm/__init__.py#L155. More informative error messages would be very helpful.

Sometimes the reason is displayed in the standard error flow in the terminal which launched jupyter.
The first thing would be to capture the stderr and display it in Jupyter.
Sometimes it is logged in the jsbml.log file if I recall correctly...
@aurelien-naldi should we capture some kind of Java exception (is that possible with py4j?) triggered by the bioLQM parsers?
