Add useful guide to start the project locally

[agilecreativity]

Thanks for a great library:

I have one suggestion that might be useful for someone to get started with the project:

git clone https://github.com/tatut/clj-chrome-devtools.git
cd clj-chrome-devtools
git submodule init
git submodule update
# then follow the guide in the README to start the REPL
# e.g. 
lein repl 
# or 
lein test

I didn't think about that, I just assumed people would use this as a leiningen dependency.

Perhaps we should have some sort of quick start guide in the gh pages and possibly the README.
I'm not certain what form of documentation would be the most helpful, but PRs are certainly welcome.

Another thing that could be useful is an examples folder with a couple of simple projects, like an example e2e test and some screen scraping example.

I whipped up a quick screen scraping example project while figuring out how to get started with this library, but to be honest, it's practically identical to chrome_test.clj.

Still, if you want the PR, just let me know.

A couple of unrelated things I noticed while working on the example project:

• Is this println intentional? It adds quite a bit of noise into the test output.
• It might be nice if to also accepted java.net.URI (and maybe java.net.URL) in addition to a string.

I don't think we need the example, if it's same as the test we currently have.

But I'll gladly take a PR to remove the vestigial println and add URI/URL support for to.

Makes sense. Maybe the README could point to the unit tests, though? I certainly found them very useful.

OK, I'll see if I can take a look.

Should the println calls be replaced with something like timbre's debug logging?

I added a note about chrome_test to README. I'm closing this issue.
