The "Site Administrator" role allows a user to create, edit, and delete activities/meters for the buildings they manage (buildings assigned by the "Administrator" to the "Site Administrator"). The user can also input data into the activities/meters. This is a higher role than the writer role which only allows users to input data. With this new role users can manage the activities/meters for their buildings.
