CRUD operations for Posts

Browse Source 
- added all CRUD operations for Post model
- add() also creates POST_BY_MEMBER and POST_FROM_NETWORK edges
- delete() also deletes associated edges
- delete() currently does not reallocate node/edge indices after deleting
- will write the data to the db.json file and global.db.nodes
