+Wrapper for MathInset * with copy-semantics

The 'atom' is the major blob in math typesetting. And 'atom' consists
of a nucleus, an optional superscript, and an optional subscript.
Exactly where the subscript and superscript are drawn depends on the
-size, and type, of the nucleus they are attached to.
+size, and type, of the nucleus they are attached to.
