Added version v0.5:

   - Core module (namespace fcloud):
        * shared objects.
        * fnode and related classes (fset, fidentifier, ...)
   - Language faupp:
        * Grammar (in bisoncpp)
        * Machine
        * Implementation of assignments, some callings,
	  name searching, and other fundamental operations.
   - Some debuggers (internal purposes):
        * A textual one (SimpleDebugger).
        * A static one (Debugger).
        * A graphical one (GraphicDebugger).

The system works as follow:

    1 A .finit file is parsed and the machine created.
    2 The machine is a fnode tree, with subtrees for the syntax tree,
      the program counter, symbol table and temporal objects.
    3 The execution process is as follows:

       a The program counter works as a stack. Its initial element is
       	 the root of the syntax tree.
       b Each step of computation depends on the top of this stack.
       c A node can push new nodes to the program counter,
         or signals its finalization. This is made by means of a node
	 child representing the actual state of computation (states
 	 pre, in and post).
       d A finished node is always popped and the previous one is other
         time executed.
       e The execution process finishes when the program counter is empty.
