- Moved from Work#getTraversedLoop

- Now Constraints is just a stack of EdgeConstraint.

- Config.summaries must be false, to disallow generation of internal summary edges with grammars.

- Previously, tabular slicing algorithms cached summary edges between runs (no longer necessary).
- SummaryTable is no longer in use, because tabular slicing is implemented without it.

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)

- 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.

- 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.
