Handling multiple enterprises at the same location

Changes:
* Introduced a cluster marker to denote multiple points of interest at
the same location
* Seperated out a plain enterprise modal into 2 parts
  * A modal called EnterpriseModal for showing a list of enterprises at
  the same location
  * A box called EnterpriseBox(which by the way is also a technically a
  modal) that shows the details of that particular enterprise selected
* If at a location there exists only a single enterprise then only the
box is shown
