Added option to omit excpetion edges in CFG

[ksons]

Pass { omitExceptions: true } as second argument to esgraph ControlFlowGraph

It's usefull if excpetions should not be considered, either by the analysis or just for display purposes.

Thanks a lot for taking an interest in this project! :-)

It would be nice to have some tests for this feature. Lets make the testing framework recognize an additional comment with a JSON options in there.

Also, I wanted to avoid pulling in escodegen as dependency. dot should take the original source as label if you have range tracking enabled. Isn’t that working for you?

Hi,

actually I didn't want to pull that commit, it was done automatically (do I have to close the pull request to avoid that further commits end up in the pull request? I see the point having another dependency.

If you want you can open another one with added tests :-)
