poor code quality

[ohze]

Sorry but can you explain the logic here: https://github.com/FolioReader/FolioReader-Android/blob/51dc6b619e51bbb354eb26d277a1c7603912997a/folioreader/src/main/assets/js/rangy-highlighter.js#L421

notes:

• oldHighlights is used out of scope
• array_diff(..)[0] may be invalid because array_diff return empty array
• use array_diff & call serialize repeatedly is in efficient
• you should add a comment for the logic here :(

I am just speechless. This whole project looks like someone left his hands there.
