Add an '--ignore' flag or similar

Reflex doesn't seem to have an easy way of ignoring certain paths. Many package management solutions for various languages (npm for node, composer for php, etc.) pull the project's dependencies into a "vendor" directory (by purpose, not necessarily by name - e.g. node uses node_modules). Since these can often be large or recursive (node) it makes sense to be able to ignore these folders for performance and FS (#6) reasons.

Imagined usage would be like so:

reflex -g '*.c' --ignore vendor/ make
# or
reflex -g '*.c' -i vendor/ make

If you'd accept a PR I can put one together.

Thanks for the suggestion. This, #6, and #9 have overlapping requirements (although I note that, if it's for performance reasons or FS limitations, only whole directory matching meets your needs).

I think this is reasonable, but I'd like to give a bit more thought about how to balance these related requests.

👍 Let me know if you'd like me to put something together

OK, this has been solved by some recent changes -- see #5 and 4c6978c for details. Basically you can do an inverse regex match like this: reflex -R '^dir/' echo filename is {}. Reflex notices that nothing inside dir/ can possibly match this regex and skips over it, avoiding the FS issues from #6.

So in your example, you can do -R ^vendor/ (or just -R vendor/, which also works but is slightly less precise as it will also ignore things like foo/vendor or foovendor).

Awesome, thanks @cespare.
