* tried to solve clang-formant test

* removed new line at EOF to get lint to pass

* feature: Added Ahocorasick Algorithm

* fixed lint using clang-format

* removed datastructures/graphs/ArticulationPointsAndBridge.java from this branch

* removed main, since test-file is added. Also modified and renamed few functions.

* added final fields to some arguments, class and variables, added a method initializePositionByStringIndexValue()

* updated to remove * inclusion and added the required modules only

* Implemented a new class PatternPositionRecorder to wrap up the position recording in searchIn()

* Added final fields to PatternPositionRecorder Class

* style: mark default constructor of `AhoCorasick` as `private`

* style: remoce redundant `public`
