/**
 * \defgroup vartype Variable Types
 * \brief A List of all Variable Types.
 *
 *	The varible types are needed for describing the content of a variable. The problem is, that only the size are not only describe the type of a variable fully (mostly because of signed and unsigned). Every time, if you want to get a variable, you get the type and size of the variable for finding it from the buffer.

/**
 * \defgroup callbacks Callback Functions
 * \brief This is a list of all callback functions, you have to call at the beginning of your code.
 *
 * This module describes all important functions, that should be declared at the beginning of the program. If you don't do that, the fully functionality of ACI cannot be guaranteed.
