Create status indicator/bar for larger graphs

[greebie]

Is your feature request related to a problem? Please describe.
GraphPass appears to do nothing when running on a larger graph. Makes it unclear whether it is working properly.

Describe the solution you'd like
Since some graphs take longer than others, it might be nice to include a status bar to show progress. Of less priority is a status bar for each process described in --verbose mode.

Describe alternatives you've considered
The current process is to use --verbose mode to see progress. Still, some processes (esp. layout algorithms) take longer than others to computer.
