Aho-Corasick Text Finder

Text finder using Aho-Corasick algorithm in Python with other additional features like text highlighting.

Implementation of Aho-Corasick algorithm in Python. Aho-Corasick is an algorithm used for Pattern Searching involving a text and many patterns. Aho-Corasick uses trie data structure to build relations between patterns with similiar characters. By preprocessing the list of pattern, we can make a trie data structure with additional failure links and succesfull links. Failure links are links used when a comparison of a pattern failed so it avoids bad string matching. Succesfull links are essentialy patterns that also matches due to being a substring of another pattern.
