Dimension of the underlying vector space

A $k$-form $\omega\in\Lambda^k(V)$ maps $V^k$ to the reals, where $V=\mathbb{R}^n$. Function dovs() returns $n$, the dimensionality of the underlying vector space. The function itself is almost trivial, returning the maximum of the index matrix.

Special dispensation is given for zero-forms and zero tensors, which return zero.

Vignette dovs provides more discussion.
