NOTE: This is a major release and as such is not backwards compatible with 2.x & 1.x

What's New:

1. New API using the builder pattern. Check the full documentation here.
2. Now, fdir, by default suppresses all errors, excludes the base path etc. To enable them use the builder functions.

What's Improved:

1. Crawling speed has been improved by upto 40%! Check the README for benchmarks.
2. The sync & async API now share the same core making it easier to maintain and fix bugs.

What's Fixed:

1. The new API allowed me to fix #12. Basically, maxDepth wasn't working properly. That has been fixed now.

And that's it. Enjoy the speed.
