Abstract base for every Capture.
Captures are applied to HTML elements with Capture::capture() which will return either a ResultPair, or an empty optional if there was nothing to capture.
Note: You probably don't want to inherit from this class directly, unless you want to provide your own Capture::clone() method. If your subclass has a copy constructor, you can extend from hext::Cloneable<YourSubclass, hext::Capture> which provides a generic clone method.
