	Classes Defined Here:

		DataCenter:		A logical/physical container for assets.  This may be a room, or
						even just a portion of a room.  It does need to be a contiguous
						space for mapping purposes.  Large data centers may want to break
						up the space into quadrants for easier management, but it can
						easily be handled as a whole (in terms of the software and database).
						Any mappings for larger than approximately 2500 SF become difficult
						to see on a laptop screen, because each cabinet takes up such a small
						portion of the overall map.

		DeviceTemplate:	A template with default values for height, wattage, and weight.
						Height and wattage values can be overridden at the device level.
						Templates are completely optional, but are a very good way to
						manage the power capacity of the data center.

		Manufacturer:	Used only in DeviceTemplate, so if you choose not to utilize
						templates, there is no need to enter Manufacturers.

		Zone:			A logical grouping of DataCenter components, so that if a large data
						center has been broken down into smaller components, it can be
						reported on as a single entity.  For example, Building A may have
						data centers in Room 100, Room 109, and Room 205.  All three can
						be placed in a single zone for reporting on Building A data center
						metrics.
