There are 2 types of groups: vendors and dealers.
Vendors are LED manufacturers, such as Olympian LED and Impact LED.
Dealers are companies such as Golden Rule Signs and Fastsigns.
Each user on the website can only belong to one group and their permissions are determined by this group. All users in the group have full control of all of the screens in which this group has access.
Inside of each group there are group admins, these users can add and remove users from the group. For example, a dealer can add their new employee.
