Rubik's Cube and Rubik's Revenge include file

This include file defines two macros which can be used to create a Rubik's Cube (3x3x3) and a Rubik's Revenge (4x4x4):

WRC_RubiksCube("...")
WRC_RubiksRevenge("...")

The parameter is a string containing rotations (an empty string is ok).

Uses actual measures of the real Rubik's cubes:

• 1 pov unit = 1 cm
• Rubik's Cube width = 5.7 cm + 0.02 cm for stickers
• Rubik's Revenge width = 6.6 cm + 0.02 cm for stickers
• The lower-left-front corner of the cubes is located at <0, 0, 0>.

Rotation syntax:

• A rotation character (U, F, L, R, B, D) rotates the correspondent outermost slice clockwise (U=upper, F=front, L=left, R=right, B=back, D=down).
• For Rubik's Revenge, if written in lowercase, rotates the inner slice.
• An aphostrophe (') immediately following the character rotates the slice counter-clockwise.
• The character '2' immediately following the character rotates the slice twice.
• Spaces between rotations are optional.

Examples:

WRC_RubiksCube("F2 D L2 D R U R L' B' D U' B' R' F2 R' U2")
WRC_RubiksRevenge("U L' F f L2 F2 D")

The last rotation can be made incomplete by declaring the following float identifier before calling the macros:

WRC_LastMoveRotationFactor

The value should be a factor between 0 and 1, where 0 means that the last rotation is not made at all, and 1 means that it's done as normal. Values between 0 and 1 will rotate it by that relative amount. (Note that in the parameter string there must not be any whitespace after the last rotation for this to work.)
