(i)R00007     - 	Slot 7 in the Imaginary dimension

Dimension - Modifier to a code in the default multiplane
Multiplane - Huge 2D area; Contains planes; Has 1048575 slots each
Plane - Large section of a multiplane; Varying size
Block - Section of a plane; Varying size
Row - Collection of 16 slots, 0-F; The n in R0000n
Slot - One cell in a row which can be allocated to an entity

Allocation - When an single entity is given a code
Code Update - When multiple entities are given codes
Reservation - Empty codes that serve a preemptive purpose, marked by [reserved] or otherwise specified
Union - Set of two codes or other unions that form a new concept - e.g. R00001+(i)R00007

Block Sizes (Bz):
Bz1 - 256     ; 16x16          ; R00000-R000FF
Bz2 - 4096    ; 16x16x16       ; R00000-R00FFF
Bz3 - 65536   ; 16x16x16x16    ; R00000-R0FFFF
Bz4 - 1048576 ; 16x16x16x16x16 ; R00000-RFFFFF

Future planes & blocks:
- All assigned!

Future Features:
- Auto-updating URL parameters
- Enter code on Table page

Dimensions starting with "x" (e.g. (xtest)) can be user-assigned and used for whatever purpose without necessarily correlating to the default dimension.
There are 65536 user-assigned codes from RF0000-RFFFFF, at the end of the multiplane.

Slots marked "[reserved]" are not to be used.

Parts of the Requested block will be assigned to third parties on request, in multiples of Bz1.
