Boilerpipe is conflicting with CyberNeko library

[GoogleCodeExporter]

What steps will reproduce the problem?
1. if boilerpipe is at a higher precedence than CyberNeko library, then it will 
cause parsing issue on user input with unbalanced tags
2.
3.

What is the expected output? What do you see instead?
Given this unbalanced HTML input 
{"$version":"<maven>project.version</maven>","pmg":false,"list":[null],"entityLi
st":[]}, CyberNeko should return the correct DOM tree
Child 1: [#text: {"$version":"]
Child 2: [maven: null]
Child 3: [#text: ","pmg":false,"list":[null],"entityList":[]}]

However, after having boilerpipe jar libray placed at a higher precedence, it 
will produce the following wrong results
Child 1: [#text: {"$version":"]
Child 2: [html: null]
Child 3: [body: null]

The root cause is the boilerpipe has copied HTMLElements and HTMLTagBalancer 
from CyberNeko. Please remove these 2 classes from boilerpipe jar
