New ToDo

All functions implemented so far must be tested. Also, some issues must be corrected before continuing. These are some that I've spotted so far:

1) All Modules
1.1) Parse the XML configuration file inside a function (this is needed due to the fact that the libxml2 functions have undesired effects in the message buffers);
1.2) Strings of fixed size (most of it of BUFSIZE, 200);
1.3) Clean up the code (remove some useless functions);
2) Global Broker
2.1) Conflict messages regarding the load update (from the Local Broker and Global Brokers);
3) Local Broker
3.1) Some hard-coded info (usually regarding the "username");
3.2) Function to check which Schedulers are alive ;
4) Scheduler
4.1) Constructor has too many parameters (when it could have only one);
8) Database
8.1) Add the Global Broker information in the table Computer, this is used in order to compute the distance between two schedulers;

After this, add the documentation using doxygen (in c++ parts), javadoc. Add Makefile, Readme, Changelog and organize the directories structures.
