## Detailed Description

Commandline and configuration file parsing helper.

Args is a commandline parsing helper. It allows giving the possible short and long options in a simple list and provides --help and --version output to the user of the program.

Usage: create an array of **shevek::args::option**, containing the desired options. create an instance of args and pass it argc and argv on the constructor. It will call all the callbacks of the options from the constructor. size () and operator\[\] can be used to access the non-option arguments.
