* This testing class gathers events from a parser and builds a stack of events.

* It is useful for checking the output of a tokenizer.

*
|
|
* IMPORTANT:
|
|
*
|
|
* The startTag event also kicks the parser into TEXT_RAW when it encounters
|
|
* script or pre tags. This is to match the behavior required by the HTML5 spec,
|
|
* which says that the tree builder must tell the tokenizer when to switch states.
