Function: Canon[CanonPrint, CanonUnPrint] - printing routines for the Canon package
tensor - a tensor expression
printed tensor - a tensor expression as printed by CanonPrint
The following commands reveal some of the internal structure:
> CanonUnPrint( _TENSOR(T[a,-b])*_TENSOR(R[b,-c]) );
The user may employ the function _SCALAR for powering of an expression with no free indices. This function has also an associated `print/_SCALAR` procedure.
