Variable for variable expansion.
A Variable is used by the KTextEditor::Editor to expand variables, also know as expanding macros. A Variable itself is defined by the variable name() as well as a description() and a function that replaces the variable by its value.
To register a Variable in the Editor use either Editor::registerVariableMatch() or Editor::registerPrefixMatch().

Expands the Variable to its value.
As example for an exact match, a variable "CurerntDocument:Cursor:Line" uses the
view to return the current line of the text cursor. In this case
prefix equals the text of the variable itself, i.e. "CurerntDocument:Cursor:Line".
As example of a prefix match, a variable "ENV:value" expands the environment value value, e.g. "ENV:HOME". In this case, the
prefix equals the text "ENV:HOME" and
view would be unused.
