		'''
		Use Selenium+SeleniumChromium to access a resource behind cloudflare protection.

		Params:
			``url`` - The URL to access that is protected by cloudflare
			``titleContains`` - A string that is in the title of the protected page, and NOT the
				cloudflare intermediate page. The presence of this string in the page title
				is used to determine whether the cloudflare protection has been successfully
				penetrated.

		The current WebGetRobust headers are installed into the selenium browser, which
		is then used to access the protected resource.

		Once the protected page has properly loaded, the cloudflare access cookie is
		then extracted from the selenium browser, and installed back into the WebGetRobust
		instance, so it can continue to use the cloudflare auth in normal requests.
