( sorry, but my english is neither as good as my math nor as my c++ ;)

Bugs and Implementation Todos:
    * Improve EReadError exception handling
      (move to integer for error status and a list of error-specific data
       e.g. the expected token, or the remaining expression string)
    * Improve the TReader<>::readNumber() method to prevent wrong input and
      parse exponential notations, too.
    * Design/implementation of an expression matching module will may be used
      for manipulating expressions (e.g. for simplifying/derivations/...)
    * design of an scripting system for solving and visualization(!) of
      mathematical problems (think about its file format (.mp/.math/...?)
      (and design for its KPart Viewer implementation)
    * simplifier: + and * gets a help method for matching left and right:
        // pseudo example:
        if (TSMatch *m = sMatch(<bool test-left>, <bool test-right>)) {
            // m->left and m->right gets auto assigned by sMatch
            // according to the match functions above
            return new TAnother<T>(m->left->clone(), m->right->clone());
        }

Feature ToDos:
  Folgende Module _muessen_ noch designed/implementiert werden:
    * symbolische Errechnung von Definitions-/ Wertebereichen und
      Definitionsluecken. (numeric_set<>???)
    * symbolische Grenzwertberechnung an Definitionsluecken und im Unendlichen
    * symbolischen Differenziale Generation (derive)
    * symbolischen Integrale Generation (integral)
    * Vereinfachung von mathematischen Ausdruecken (simplify)
    * Expandierung von mathematischen Ausdruecken
      (d.h. Reduzierung auf den Grad 1, soweit moeglich)
    * Scripting System zur Loesung und Visualisierung mathematischer Probleme
    *
