Add Findfiles func to find files recursively

[mainawycliffe]

Add a FindFiles func that will find files recursively in all directories (#35)

NOTE:

I wanted the method to accept glob, but its behaving strangely in go. When you pass dir/**/*.txt, it only finds files inside the subdirectories ignoring all files in the root directory.

Are you ready for a review yet @mainawycliffe or are you still working on it?

[mainawycliffe]

I am ready for a review. I think we can add glob to FindFile func if the situation changes in the future.

[bitfield]

Thanks @mainawycliffe! This looks great. Just a few nitpicks I've pointed out.

[bitfield]

Great work!

[mainawycliffe]

I am Sorry, I accidentally merged my branch on #23 and became too tangled to undo. I think the example is also for a review, so you can take a look at that too.

[bitfield]

Looking good! Everything with the FindFiles feature is complete, I think, so it's just finalising the details of the todos example now.

[mainawycliffe]

no problem @bitfield, that happens all the time.

[bitfield]

Looking good! Just a couple of minor tweaks to give this the final polish!

[mainawycliffe]

Taken care of the changes requested above.

[bitfield]

Great work, @mainawycliffe! Do you mind if I give this a final pass for style, consistency, squash commits, etc?

[mainawycliffe]

No, I don't.

[bitfield]

Thanks again for the feature, and all your patient collaboration @mainawycliffe.

[mainawycliffe]

Thanks too, learned a lot. Any new issue that I can work on?

[bitfield]

I think what we could most use is some substantial, non-trivial, useful programs written using script. If they're easy to write, they'll make great examples and demos. If they're not, that may be pointing us towards improvements and additions in script that would make such programs easier. See what you can come up with!
