First approach to own SSI Dijkstra Fast data-structures for updating the algorithm to the UKB 2.0 version.

* Added csentenceSSI.cc
* Added csentenceSSI.h
* Changed csentence.h (Added a method for checking if word is a type of cw_ctxwords)

TODO:

* Check the utility of m_V2 on this project (probably, none).
* Recode SSI-Dijkstra+ using our own already coded AND checked versions of csentenceSSI.
* Check the coding standards for UKB.
Second approach to own SSI Dijkstra Fast data-structures for updating the algorithm to the UKB 2.0 version.

* Makefile modified for compiling our new data structsa nd classes.
* Changed csentence.h (Added a method for checking if word is a type of cw_tgtnopvwords)
* Adapted the code for UKB Coding Standards (we need to check it, although).

TODO:

* Check the utility of m_V2 on this project (probably, none).
* Recode SSI-Dijkstra+ using our own already coded AND checked versions of csentenceSSI.

A LOT of compilation errors are in this version of the code.

TODO TOMORROW:

* Just check the calls to get_vertex_by_name and adapt it for the new UKB version (bool, Kb_vertex_t).
* Check what is going on the calls to dijkstra_shortest_paths.
First real approach to a functional version of the code (at least, on a UKB 2.0 version scope and using the "old" implementation of SSI-Dijkstra+ (not the fast one).

A LOT of changes:

* KbGraph class is now the responsible of all the Dijsktra algorithm calls (I tried to do on my own class, but it failed probably because of the new impementation of the graph structure) 
* Changed a lot of stuff on the SSI classes heading towards problems between old program (using CWord for all the implementation) and new code.
* Adapted the code for UKB Coding Standards (I think I did it right, I hope).
* Erased m_V2 attribute on SSI classes (no real use on the project).

TODO:

* Hey, why this doesn't work? Nobody really knows :(
Changes:

* SSI-DijkstraFast implemented (probably some bugs are there for us to find them)

TODO:

* Hey, why this doesn't work? Nobody really knows :( <- THIS
Changes:

* Finally a version that compiles and works (HOORAY!).

* We need to prove correction of all this bunch of code, though.
Changes:

* POLY option finally works.

* A little cleanup looking forward the final version
