\defgroup jkqtptools Tool Functions and Definitions for JKQTPlotter
\defgroup jkqtptools Support Function library (e.g. for JKQTPlotter)
This group contains a set of tools that I've written over the years to enhance the
C++ standard library.
This group contains several tool functions and datatypesthat are neccessary for
JKQTPlotter, JKQTMathtext and the other major classes in this library, but may
also be used separately. The functions and datatypes are sorted into several
functionaly groups.
