MacroUnexpander applies the structural formatting of expanded lines into
UnwrappedLines to the corresponding unexpanded macro calls, resulting in
UnwrappedLines for the macro calls the user typed.

Summary:
The MacroExpander allows to expand simple (non-resursive) macro
definitions from a macro identifier token and macro arguments. It
annotates the tokens with a newly introduced MacroContext that keeps
track of the role a token played in expanding the macro in order to
be able to reconstruct the macro expansion from an expanded (formatted)
token stream.
Made Token explicitly copy-able to enable copying tokens from the parsed
macro definition.
