Improve the new git repo command

The new git repo command doesn't handle file paths yet, and it forces users to dump all repository data at once instead of just requesting what they need. This makes scripting difficult and forces developers to keep using the older git rev-parse command. This project improves the git repo info command in two main ways: First, by adding path.* keys (like path.git-dir) that can return both absolute and relative paths. Second, by building a fast, lightweight search system (O(log N)) so users can easily query specific categories of information. As a stretch goal, the project will evolve git repo structure into a diagnostic tool by introducing metric distributions, such as object size and entry histograms.
