/**

|
Abstract base class for all math objects. A math insets is for use of the
|
|
math editor only, it isn't a general LyX inset. It's used to represent all
|
|
the math objects.
|
|
|
|
Math insets do not know their parents, a cursor position or things
|
|
like that. They are dumb objects that are contained in other math insets
|
|
(InsetMathNests, in fact) thus forming a tree. The root of this tree is
|
|
always a InsetMathHull, which provides an interface to the Outer World by
|
|
inclusion in the "real LyX insets" FormulaInset and FormulaMacroInset.
