description:
Added integer member rank to all objects,
changed initialization of free_indices to
be independent of rank,
introduced helper functions is_true_scalar(foo),
is_scalar_valued(foo) and rank(foo) to be used
instead of referencing these variables directly.

A "true scalar" is a scalar valued expression
with no free indices, f.ex. is u[i]*v[j] not
a true scalar since it represents a set of scalars,
but it is still scalar valued and not a tensor.
(Assuming u,v vector expressions and i,j indices).
