Token context defines the environment in which only a limited set of tokens
can be used. This set can be retrieved by calling the getTokenIDs()
method. The context can contain other contexts which means that the context
can possibly switch into one of its children contexts during lexing. The
child context can also have other children that can work in the same way. In
this way context-paths can be created. They describe the way how was the
token lexically recognized. The context can be retrieved when the
syntax-class is known using the get method.
