Added runkeeper script. New bin/ directory for script stuff
Improved runkeeper script with (distance, speed) graphs and easy run history visualization.
runkeeper: Point labels now show distance and duration, instead of distance and speed.
runkeeper: Inverted the graph, now points are (speed, distance). Printing the images directory.
runkeeper: Fix min/max typo.
runkeeper: Moved authentication token out of the code, now sourced from a runkeeper_auth file.
runkeeper: envelope comparison. Given a set of tokens, computes the classical graphs for each (in separate directories) and plots all envelopes together in a separate graph.
runkeeper: Only show envelope comparison when there are several users.
runkeeper: Better error handling when there are no runs for a user.
runkeeper: stricter plot boxing.
