Also implemented in subsumed version.

WorkNS didn't take into account lastEdgeType, causing incompleteness errors in slices.

- Extends JGraphT's DefaultEdge
- Removed equals and hashCode (were equivalent to Object's)

Partial benchmarks: only timing or only slices.

- ConstrainedTabularAlgorithm:
  - Unified State and MState, moving the last edge type to Work.
  - For efficiency, don't store the last edge type unless it is relevant.
  - Removed assertions.
- ConstrainedSubsumedTabularAlgorithm: added map to speed-up lookup of subsumed work objects.

- Tabular algorithm: only traverse intraprocedural edges by default.
- Improved subsumption checks in tabular algorithm.
- Corrected actual-out detection.
- Added assertions to check for incorrect interprocedural edges.
- Control-flow is incorrect in anonymous routines: it produces interprocedural control dependence.
- Parametrized erlang server connection settings.
- Added new comparisons for benchmarks.
- New script to run benchmarks and analyze results with SQLite.

- Worklist approach implemented through a Config flag in SummaryTable.
- Unconstrained and constrained variantes (TabularAlgorithm & ConstrainedTabularAlgorithm). The constrained version features a limit to the size of the stack.
- Constrained subsumed variant for efficiency (ConstrainedSubsumedTabularAlgorithm).
- Efficient EdgeList (linked-list) to store edges visited through a traversal.
- Bump language level to 16.
- eKnife cli: added switch to use tabular algorithms.
- Moved benchmarks out of eKnife and BencherTest.

- ️️SummaryTable: actual-out node may none or multiple matching formal-out.
- EDG, SummaryTable: get and clear methods for stats.
- EKnife, BencherTest: adapted for benchmarks in which running the benchmark alters the graph itself.

- Move summary settings from EDGFactory to Config.
- The EDG now contains a SummaryTable, a map which computes summaries on-the-fly.
- ConstrainedAlgorithm: now looks up summary edges in SummaryTable.
- Fixed typo in SummaryEdgeGenerator#generateOnlyExternal.

- Add flag to EDGFactory to enable the creation of interprocedural edges.

- A flag has been added to make slices intraprocedural if desired.

If you are performing benchmarks, you should revert this commit and manually start the server, because it affects the speed of the slicer (the parser step).

- Remember, to run benchmarks you require a "server" process for Erlang (see previous commits).
- If you output slices, astCounter.erl can be used to count the number of AST nodes in a given program.

- Full support for records, with their own access constraints
- e-Knife can now print Erlang code that contains newly supported data structures (record, bin, try, catch, throw...)

- Basic support for records, bin, float, try, catch
- Feature to count access constraints traversed
- Feature to count access constraints present in the graph
- Bugs fixed:
  - Can handle empty string represented as list `[]`.
  - Can handle other unary operators apart from `-int`.
  - Can handle nested list comprehensions.
- Now requires a running instance of erlang, use the following command:

    erl -pa (pwd)/e-Knife/src/main/resources -name server@localhost -setcookie erlang -noshell

- BencherTest now accepts `-DiterGen=NUM` and `-DiterSlice=NUM` as Java arguments.
