class MushRotation
# Class: MushRotation
#
# Description:
#
# This object contains a 4D rotation, which can be used to rotate vectors or other rotations.
#
# Method: new
#
# Creates a new MushRotation object.
#
# Parameters:
#
# None.
#
# Returns:
#
# New MushRotation object.
#
# Default:
#
# The MushRotation object returned by new is the identity i.e. provides zero rotation.
# Non-zero rotations can be obtained from the <MushTools> object.
#
# Example:
#
# (example)
# rotation1 = MushTools.cRotationInXYPlane(Math::PI/2)
# (end)
#
# Method: mRotate
#
# Applies the rotation to another object.
#
# Returns:
#
# None.
#
# Paramaters:
#
# This method takes either a vector or another rotation as a parameter. If the parameter
# is a <MushVector>, it rotates the vector. If another <MushRotation>, the parameter
# is set to a combination of the original rotation followed by this rotation.
#
# Example:
#
# (example)
# vec1 = MushVector.new(1,0,0,0)
# rot1 = MushTools.cRotationInXYPlane(Math::PI/2)
# rot1.mRotate(vec1)
# # vec1 is now (0,1,0,0)
#
# vec1 = MushVector.new(1,0,0,0)
# rot1 = MushTools.cRotationInXYPlane(Math::PI/2)
# rot2 = MushTools.cRotationInYZPlane(Math::PI/2)
# rot2.mRotate(rot1)
# # rot1 is now a rotation that applies the original rot1 then rot2
# rot1.mRotate(vec1)
# # vec1 is now (0,0,1,0)
# (end)
#
# Method: ==
#
# Tests whether two rotations are equal.
#
# Returns:
#
# Boolean.
