Add component: Pivot table

To make analyses fit the business needs better, we are interesting in adding one more component type.

We would like to have a pivot table that would allow drilling down, especially helpful for hierarchical data. E.g. continent-country-city-office or date-driven: year-quarter-month-day.

This request came from an end-user.

This feature is a basic feature avaialble in other PM/BI tools, hence it would be beneficial for ARIS to offer it.
