Implement String Algorithms

[manrajgrover]

String Algorithms to be implemented are:

• KMP Pattern Search
• Rabin-Karp Pattern Search
• Aho-Corasick Pattern Search
• Z-Algorithm Pattern Search
• Levenshtein distance
• Longest common subsequence
• Longest common substring
• Longest common leading/trailing substring
• Dice's coefficient

I'm on the longest common *strings/sequences

[Bladefidz]

I am interested with KMP and Rabin-Karp. Hope will be send you two pull requests next week.

I will take Longest common substring

[IamMayankThakur]

I would like to work on Dice's coefficient. Will submit the merge request this week.

Hi, I would like to take up Z-Algorithm Pattern Search. Should I do ahead ??

Created PR for Aho Corasick string algorithm.
