CrawljaxConfiguration has URL lists but no getters yet

Added simpleExample
Added ArrayList<URL> urls to CrawljaxConfiguration
Crawljax aware of additional URL added via alsoCrawl(), but cannot open it yet
Ported my code from the old code, but it has Firefox Driver error

Is it because of new feature implemented? or maybe I forgot to port
some code...
Enhancement implemented.
