#mongoose-tags
A simple tagging plugin for Mongoose (fork of mongoose-taggable).
Adds the ability to add and remove tags to a document, and find models filtered by tags. Uses safe atomic updates to avoid race conditions.
NOTE: Indexes are not applied to the tags path, because you should probably use a compound index with other paths in your schema
##API

@param {String} tag The tag to add
@return {Boolean} False if tag already existed; true if added
###model.addTag(tag, cb) Add a tag to a document atomically
NOTE: This method modifies the document on the database
- @param {String} tag The tag to add
- @param {Function} cb Callback(err, addedTag) addedTag will be false if tag already existed; true if added
###model.removeTag(tag) Remove a tag (in memory only)
@param {String} tag The tag to add
@return {Boolean} False if tag didn't exist; true if removed
###model.removeTag(tag, cb) Remove a tag from a document atomically
NOTE: This method modifies the document on the database
- @param {String} tag The tag to remove

##Changelog ###v0.5.0
- Changed the way excludeTags works in filterByTags(), from an AND operation to an OR operation. The method now selects items that have ALL of the includeTags but filters out items that have ANY of the excludeTags.
