Class Difference
java.lang.Object
com.github.javaparser.printer.lexicalpreservation.Difference
A Difference should give me a sequence of elements I should find (to indicate the context) followed by a list of elements
to remove or to add and follow by another sequence of elements.
I should later be able to apply such difference to a nodeText.

combineRemovedElementsToRemovedGroups
Maps all Removed elements as keys to their corresponding RemovedGroup. A RemovedGroup contains all consecutive Removed elements.
Example:Elements: Kept|Removed1|Removed2|Kept|Removed3|Added|Removed4 Groups: <----Group1----> Group2 Group3 Keys: Removed1+Removed2 Removed3 Removed4
- Returns:
- Map with all Removed elements as keys to their corresponding RemovedGroup
