fastgrep - a faster "grep -r"
--------
A utility similar to `grep -r ...` but focused on raw speed and utilization of system resources. This tool
is useful for quickly scanning large directories for files containing a specific string.
The intro gif is fastgrep scanning the entire, un-indexed, `1.15.1 craftbukkit` sources on a Kali Linux install
running on an 4-core laptop CPU (the `i7-8550U @ 1.8GHz`) for the string "createInventory". That is around 1 million
lines of code searched in under 100ms. The same scan would take grep several minutes.
```
$ cd ~/craftbukkit-1.15.1-src
$ cloc .

This functionality can be very useful for developing or modding large, documented, codebases
(e.g. open-source or reverse engineered games, operating systems, etc.).
