 We have nested lists to represent the Tex document.
 Each element of a list of chunks can be one of:
  - a plain string
  - a macro with/without arguments. Arguments are lists of TexChunks.

Example (\toplevel is implicit but made explicit here):

AddMacroDef(ltMYMAT, "mymat", 2);

\toplevel{The cat sat on the \mymat{very coarse and {\it cheap}}{mat}}.

Parsed as:

TexChunk: type = macro, name = toplevel, no_args = 1
  Children:

    TexChunk: type = argument

      Children:
        TexChunk: type = string, value = "The cat sat on the "
        TexChunk: type = macro, name = mymat, no_args = 2

          Children:
            TexChunk: type = argument

              Children:
                TexChunk: type = string, value = "very coarse and "
                TexChunk: type = macro, name = it, no_args = 1
