Estimate accuracy and status updates

As developers work through their tasks, they log time either through their IDE or directly on the cards on the task board. Indicating the time spent on an issue will automatically reduce the time remaining based on the original estimate and update the hour burndown chart. If the original estimate was slightly off, providing an more accurate estimate of the time remaining will update the sprint summary for the team to plan accordingly. The hour burndown chart also tracks estimate accuracy throughout the sprint to help the team plan for future iterations.
