tree features

Suppose we want to get the path along the dependency tree from "HAL-9000" to "I". Also, suppose we somehow have constituents in the dependency tree corresponding to these.

The path string:

 
	System.out.println(PathFeatureHelper

#

Clauses

	SpanLabelView clauseView = (SpanLabelView) ta
