## Detailed Description

Argument Parser Class.

Author
  Thomas Eriksson and Pal Frenger (Thanks to Svante Signell for valuable input)

This class parses strings to variables. The syntax is compatible with Matlab and Octave. It can be used in several different ways. See the Detailed Description in the Argument Parser module.
