WARNING: DO NOT IMPLEMENT YET - TO BE DISCUSSED.

Use a more intuitive syntax, where methods are called on the document element being modified instead of the accessors.

See https://github.com/hibernate/hibernate-search-6-poc/commit/f07d3c2a5278c8c1baaa32ef803e57d4d6653b79:

This:

DocumentElement borrowalsObject = borrowalsObjectFieldAccessor.add( target );			
shortTermBorrowalCountAccessor.write( borrowalsObject, shortTermBorrowalCount );

Would become this:

DocumentElement borrowalsObject = target.addNew( borrowalsObjectFieldReference );
borrowalsObject.add( shortTermBorrowalCountReference, shortTermBorrowalCount );

We may want to do the same for entity accessors, to be consistent.

Note that in order for this to make sense, we would have to rename the "accessor" to a "reference" or some similar term expressing the fact that this object is "passive" by nature (on contrary to an "accessor").
