EDIT

The new single default cache strategy for Reference.

As we do have only one Reference class left which implements multiple interfaces, we may also only need 1 single cache strategy. However, care must be taken as the formatting differs dependent on the type an the in-reference structure.

Generally the cache strategy allows 3 formattings:

• for bibliographic references (stored in {@link Reference#getTitleCache() titleCache}).

• for nomenclatural references (stored in {@link Reference#getAbbrevTitleCache() abbrevTitleCache}), but without micro reference (detail).

• for nomenclatural references with micro reference, but not stored anywhere as the micro reference is part of the name, not of the reference

• for short citation (e.g. Author 2009) as defined in {@link IReferenceBaseCacheStrategy#getCitation(Reference)}

• the fullAbbrevTitleString which is the same as the titleCache but using the abbrevTitle instead of titleCache if possible, not stored in any cache

Also remove the rectifyCacheStrateggy method in Reference as it sets the old cache strategy.
