## InverseMetric

Make a two-tensor an inverse metric.

This property is the partner of `Metric`

. It makes the
associated two-tensor symmetric and also indicates that it can be used
to raise or lower indices.g^{m n}::InverseMetric.
g_{m n}::Metric.
ex:=g_{m q} g^{m n} A_{n p};

\(\displaystyle{}g_{m q} g^{m n} A_{n p}\)

eliminate_metric(_);

\(\displaystyle{}g_{q}\,^{n} A_{n p}\)
