Display some numbers about how much cycling you've done this year and how you need to adjust to reach a certain goal. Pulls data from a strava profile.

#
#  This script parses a strava athlete page to get the amount of bicycling kilometers this year 
#  to date from strava, and calculates some statistics from that (km/day and km/week to date and
#  necessary to hit a target, and km to go / km already done).
#
#  usage: $ ./kmtogo.py [target]
#  If no target is specified, it'll take the default value (2000).
