This is a complete revision and extension of the original "tensor" package by
Mike Piff; it defines commands for typesetting tensors with mixed upper and
lower indices.  Correct pre-pending of indices is now possible while backwards
compatibility is maintained.  A command to typeset nuclides is also defined.

The use of tensors with mixed upper and lower indices, in which the relative
horizontal positions and spacing are significant, is common in both physics and
mathematics.  The commands defined in this package automatically maintain
correct positioning.  Spaces in an index list may optionally be filled with
dots or other suitable symbols.  Another usage addressed by this package is the
pre-pending of indices.

Two math-mode commands, \tensor and \indices, are defined (one of which,
\tensor, remains backward compatible with the original definition by Mike
Piff). A new text-mode command, \nuclide, to typeset nuclides is also defined.

Change history:

starred form of \indices, minor spacing and LaTeX code improvements.

v2.0 first official release of extended version.

v1.0 last official release of original version.
