git integration with log code

[mrjeffs]

build function that compares code from log function with git version control by diff of current module and date of log.

[JasperVanDenBosch]

We can use GitPython for git integration.

Basically the goal is to be able to obtain the original code used and compare it to a local or newer version.

If a path to a script is given, use that, otherwise default to current directory.

What do we want to gather?

• commit hash
• committed_date
• current branch?
• remotes?
