WeightOf

• WeightOf[expr] gives the weight of expr as a tensorial density.

• A weight is always a linear combination of names of bases. It is 0 if expr is not a density.
• The weight of the basis-determinant of the metric is defined to be 2*basis.
• See: Section 4.4.
• See also: WeightOfTensor, WeightedWithBasis.
• New in version 0.
