Feature: Highlight regex capture groups in terminal output

[brycefisher]

My favorite feature of behave, a Python port of cucumber, is the capture group highlighting. This is helpful for two reasons:

• It helps validate complex regexes during step development
• It informs someone viewing the output which portion of the step is dynamic and could be modified

When validating how easy this would be to add, I found that the current implementation of using Examples: sections actually didn't do what the user would expect, so has been removed until it does.

It didn't actually handle the variables in the tests, so it effectively didn't do anything but print skipped for them all.

@brycefisher I'm currently reviewing the output of this tool, so if you had some screenshots of this behaviour it would be helpful for me. 😄

Hi @bbqsrc ! Sorry for the delay. Do you mean the python package behave? I can gladly show some screenshots if so

[bbqsrc]

yeah, please do :)

I can toss in one, right of my dev station

As you can see the parts in lighter shade of green are regexp captures

[bbqsrc]

Aha! This would require some changes to some events but not inconceivable.

It's pretty useful when debugging with command line, less when you use integrated tools (but that's a separate ticket, as I want tests from here to work in clion damn it! :D)

Resolved in #136. Now captures are higlighted with a bold style.
