User stories:

As an event organizer, I want to be able to set a goal for my event, so that participants are motivated to join and contribute based on the goal, and so that I can have a clear story of the event outcome based on the goal.

As an event participant, I want to know how my contributions help accomplish the goals of the event, so that I can understand the impact of my edits and of the event overall.

Acceptance Criteria:

• Given that an event has a goal set,
  • A progress bar should be displayed in the Contributions tab for EventDetails
    • And it should have the following text & formatting:
      • Header: "Progress to goal" (in bold)
      • "The organizers of this event have set a goal of [X quantity] [Y task]."
      • Percentage complete should be in top right corner
      • Progress bar should display progress complete
      • [A quantity] of [B quantity] [c task type]"
• And if contributions related to the goal have been made,
  • The progress bar should be updated to display the change against the goal
• And if contributions related to the goal have not been made,
  • The progress bar should still display, but it should not be shaded in at all
• And if the goal has been met,
  • There should be text next to the %, so that it reads as: "Goal exceeded by [X]%"
    • And X is the percentage exceeded (for example, 110%)
