Zooma3 - Annotation Create, Update, Replace

[olgavrou]

When a new Annotation is saved into Zooma it will first go through mongo.
Loading through spreadsheet should support:
adding new annotations
annotations should generate a hash like old zooma did
can not load duplicate annotation based on hash
updating annotations if the annotation id is provided
this means that we should return a spreadsheet where the annotations will be populated with there annotation mongo id so the spreadsheet owners can then update the annotations that they want
updating an annotation should create a new document that points to the old one (replaced by functionality)
deleting NOT supported through spreadsheet
up/down voting NOT supported through spreadsheet
Propagates to Solr which either up votes the annotation summary and adds the source, or creates a new annotation summary
Propagates to Neo4j which can (a) create an annotation (b) if needed add the replaced by relationships
Up/Down Voting:
Should be supported through the API
Creates a new document in mongo that will up/down vote the annotation summary in Solr and add/remove the source from it
Create a new annotation in Neo4j
