 * This operation initializes all the local variables reading a configuration
 * file. For every variable a macro like READ_INT() is called passing it the
 * input filename and the variable to be written to. This macro calls
 * an operation read_int() augmenting the parameter set with the name of the
 * variable to be read. The read_int() operation parses the input file, extracts
 * the value of the variable, sets the variable and finally prints some debug
 * information. This is possible as the macro adds the name of the variable to
 * be set. All the helper operations can be found within helper.hpp and helper.c.

 * @param szFileName char pointer to the filename
 * @param config Config struct containing all configuration options
