A data flow node corresponding to a class definition or a function definition acting as a class.
The following patterns are recognized as classes and methods:
class C {
method()
}
function F() {}
F.prototype.method = function() {}
F.prototype = {
method: function() {}
}
extend(F.prototype, {
method: function() {}
});
Additional patterns can be recognized as class nodes, by extending DataFlow::ClassNode::Range.
