Issue #2 : links have been updated. currently, the link redirects to the regex documentation for the current rust release

Feel free to ignore the "purge greps" commit.
That was supposed to stay on my fork until I at least make sure I didn't break anything.
And it's terribly inefficient since I am focusing more on making sure I know what the code does than on efficiency at the moment.

I think the link should be a docs.rs link, so we can pin the version number to what we’re using.

[wolvespaw]

I'll look into it.
Do you know what rust build was used?
(would be a bit faster than tracing through the code)
With how it's written, it looks like the regex version will be tied to which version of rust it was compiled with.

[ashfordneil]

regex hasn’t been part of rust itself for quite a while now, it’s just an external library. The version number used is in cargo.toml and cargo.lock, but the latest version number available is on https://crates.io.

@ashfordneil the ink is now pointing to the regex library version currently in use.
still need to update the regex library since it's behind by a major version (in use 0.2.6, current: >1.0)
