* added direct test check i.e. defining a variable expected and just checking if res and expected are equal.

* Created New Class Trie, merged 'buildTrie and buildSuffixAndOutputLinks' with 'Trie constructor'. Merged setUpStartPoints with searchIn. Now AhoCorasick contains -> inner class: Trie, Node. Methods: search and convert. Trie has -> Methods : constructor and searchIn

* Updated TestFile according to the updated AhoCorasick Class. Added Few more test cases

* minor chage - 'removed a comment'

* 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`
