class_docstr: An instance of this class converts a string of a Wolfram Mathematica
  expression to a SymPy expression.
  
  The main parser acts internally in three stages:
  
  1. tokenizer: tokenizes the Mathematica expression and adds the missing *
      operators. Handled by ``_from_mathematica_to_tokens(...)``
  2. full form list: sort the list of strings output by the tokenizer into a
      syntax tree of nested lists and strings, equivalent to Mathematica's
      ``FullForm`` expression output. This is handled by the function
      ``_from_tokens_to_fullformlist(...)``.
  3. SymPy expression: the syntax tree expressed as full form list is visited
      and the nodes with equivalent classes in SymPy are replaced. Unknown
      syntax tree nodes are cast to SymPy ``Function`` objects. This is
      handled by ``_from_fullformlist_to_sympy(...)``.
