Construct a single range overlay address space.
NOTE: The same name should not be used more than once within a given {@link AddressFactory}.
@param name overlay space name
@param baseSpace overlayed base space
@param unique unique index number
@param min min address offset
@param max max address offset
@param orderedKey ordered key which is used during comparison with other overlays.  Within
program-based implementation (i.e., ProgramOverlayAddressSpace) this is auto-generated based 
upon the initial name and must be unique within the associated AddressFactory which does not
exist for this test implementation.
