Idea: Github API reverse search

Goal: Teach a usage of github API, basics considerations for searching

Question: Given a commit hash, partial hash and author name, and author name plus commit message

Solution: Search for the names of the repositories for commits, and provide the hash of the string concatenation of the three repository names (i.e. sha1sum(repo1_name + repo2_name + repo3_name) )

Optionally the solution may be required in a short amount of time, s.t. a naive search solution would not suffice
