/************************************
  What you will see here are the function definitions from the header file (network_manager.h) with doxygen documentation. Here is an example:


 In file network_manager.h

 class NetworkManager
 {
   int doSomeStuff(float argument, float* pointer);
 }

 will be implemented in the source file as follows:

 In file network_manager.cc

 / **
  *  this is the short description for this function: it just does some stuff
  * @param argument: this is the first argument, stuff...
  * @param pointer:  this is the pointer to nowhereland
  * return: whatever the function returns: for example an index, number, etc.
  * /
 int NetworkManager::doSomeStuff(float argument, float* pointer)
 {
   // whaterver you want to do
 }


 if you want to make automake compile your files: you will want to add the file names to the local Makefile.am
