Default Reports - Add a statistics table

[kflemin]

On the Default Reports page, under the charts, add a table listing a few statistics about the data in the chart. We would like to display the following for each axis:

• sum
• mean
• min & max
• 5% (5th percentile)
• 25% (25th percentile)
• 50% (median)
• 75%
• 95%

Additionally, if a user has selected a particular access level instance and that instance is not a leaf node, add rows in the table to display the statistics for each Access Level Instance included in the selected instance level (just 1 level down). If there is no access level selected or the org has no access levels, then the table would have a single row.
