Create Number of Visits with visit type for given location and date report

Reference Meta Data module has Visit report which can give a number of total visits for given date period. The content of that report doesn't enough for a better report. So it should be improved with following contents,

• Total Number of visits grouped by visit types.
• Users should able to get the visit report for all locations or a given location.
• Bar chart should be added into the bottom of the report as usual.
• Add support to include the active visits into the report
