As a user, I want to level-up my character, based on my achievements and in-app progress

Each task has a number of points associated with it. When the task is completed, that number of points should help increase certain user stats proportionally.

Requirements

• With each task completed, have the user's stats go up
  • update the stats progress bar, so that it reflects the user's improvement
  • level up a stat if needed; this new level should need more points to be completed
