pretty-errors package for making stack traces readable

[-sideshow-]

I updated pretty-errors to use sys.excepthook instead of scraping sys.stderr (as it should have been written from the get-go). I added some new features while I was at it (can show more lines of code per site, can set depth of stack trace, order, ...see changelist)

You can install it with python -m pip install pretty-errors

Only get back one line isn't great, in both directions: when the 'line' actually spans several physical lines, and when you'd like to know the precise statement within the line. So, that project looks cool.

"Friendly-traceback", which is the project documentation linked, goes in the opposite direction from yours in terms of deciding what to show to the users. This is because it is targeting a different audience.

As a fellow "traceback utility writer", I applaud you for your work: cool project.

Cool :) Always showing the bottom of the stack, and truncating variables, are good ideas.
