[New Feature Idea] - Add summary report for investor meeting / update

[sgering]

When using oreline in a production workflow, it would be useful to show daily or periodic progress with shareholders. The investor update would allow users to show changes for a specified period. For example, the weekly report could include meters logged for the week, average grade, expected meters to target depth etc, If the user enters the cost per drilling meter, we could calculate the costs as well.
