Various points:

- Completed adding overloaded operatos on the class files. All of them (the leaf
  classes, at least) can be readed from a file (the file must have the same format
  as the CIF finite state machine defines, and there must be spaces to split the
  components of the commands) and stored to a file. The commands are stored in
  the cleaned format.

- Added the EndCommand class file to the source tree (still to update the Dia file).

- The first tests show correct loading and command handling. Larger tests are comming.

- The final documentation process is about to begin.

- The library reaches an usable state. Is still needed some tests to find errors, but
  the classes can be used now.
