Return whether two quaternions are equal. They are considered equal when their difference is
less than or equal to the precision.
@param a the first quaternion
@param b the second quaternion
@param precision if abs(a.comp - b.comp) <= precision for every component comp (x, y, z, w), a and b are considered equal
@return whether a and b are equal
