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
The enterprises have related producers and hubs that need to be
dereferenced. Therefore, we need a bigger set of enterprises to be
loaded. Injecting all enterprises is simple and doesn't require changes
if the set of needed enterprise data is growing in future.
