* Arity added to tuple elements
* Stack states correctly updated (considers the previous traversed edge to differentiate states)

- Generators implicit and explicit restrictions are now more accurately treated
- Created +-[]S (List structure constraints)
- Created +-{}S (Tuple structure constraints)
- New kind of edges (ValueStructural Edges)
- Prevented the interference of the traversal of (Black) Structural Edges with other edges

* .erl -> original program
* .criterion -> slicing criterion (line var)
* .goldStandard -> minimal slice
* .sliced -> slice computed by the slicer

* Erlang script path defined
* Fixes in code generation: some sliced expressions removed instead of replaced
* Fix guard stacks in CFG generation
* Logic simplification in Node-Result creation process
* Fixed dead clause detection
* Improvements added to summary generation:
    + Function calls associated to a particular formal-out-formal-in summary edge are only repended when the grammar term is created, and not for each added production
    + The list of constraints stacked after an AsteriskConstraint are removed when another AsteriskConstraint is pushed to the stack

* Call arcs to clause nodes

* Traversal restriction of Generator value edge traversal
* CFG limitation for unreachable code

* The CFG ignores unreachable clauses in if expressions
* High order call slicing improved
* Fix Anonymous routines lack of value dependencies

* AdHoc anonymous function calls (fun(X)-> X+1 end(5))
* Named anonymous function / function calls

* Anonymous functions considered (fun(X) -> ... end)
* Shadowing in Anonymous Functions and LCs improved

* ast.erl and saver.erl has been moved to e-knife resources folder
* CFG and Value arcs are now in e-Knife
* CFGs are built with a the visitor pattern
* The graph library is now jgrapht
* CFGs of the clauses of the same method are now independent
* Interprocedural clause matching has been improved to not link unreachable clauses
* Shadowed variables and its value are now delimited to their context
* Classic algorithm has been added to slicing computed algorithms
