Re-calculate visitCount for dimension(s)

Name of related component: Data Export API

Request summary:
Re-calculate visitcount for a couple of dimensions. We would like to gain 
insights into how often people navigate to specific pages (page-level 
customVariable) to determine stickyness. Besides that, we would like to 
identify which traffic sources bring in new visits, and which bring in 
returning visits (calculated specifically for each medium/source combination), 
and how often those people come back.

Use Cases:
- Insights into content quality (how often do people return?).
- Insights into navigational versus other traffic flows (to optimize AdWords 
traffic. we would like to avoid our adwords campaigns to be used as navigation 
and turn off those campaigns / adgroups since for those campaigns we are 
spending money on clicks that will find other ways to navigate to our content).
