/*

   The base install of CAMP2.

   Just track devices. A device can be any arbitrary item.

   A device has one owner, and is located at one location (location)

   A location also has an owner. Devices can be located on locations

   owned by a different owner, ie when a device is lent to a owner

   or colocated at a third party NOC.

   This is very basic. It only tracks device ownership and locations,

   and movement between them (via the created and removed fields).

   When a device is moved to a different location, or sold to a different

   owner, the old record in the linking field has its removed field 

   updated and a new record created with a created date. With this, we

   can track the lifespan of a device.

   It is assumed various modules will be created to extend the capabilities

   of this basic structure. However, modules should not modify the basic

   database structure, instead creating new tables that link into

   these tables.
