/**
* CTAKESParser decorates a {@see Parser} and leverages on
* {@see CTAKESContentHandler} to extract biomedical information from
* clinical text using Apache cTAKES.
* It is normally called by supplying an instance to
* {@link AutoDetectParser}, such as:
* AutoDetectParser parser = new AutoDetectParser(new CTAKESParser());
*
It can also be used by giving a Tika Config file similar to:

*
Because this is a Parser Decorator, and not a normal Parser in
* it's own right, it isn't normally selected via the Parser Service Loader.
