DBCollection help
	db.users.find().help() - show DBCursor help
	db.users.count()
	db.users.dataSize()
	db.users.distinct( key ) - eg. db.users.distinct( 'x' )
	db.users.drop() drop the collection
	db.users.dropIndex(name)
	db.users.dropIndexes()
	db.users.ensureIndex(keypattern[,options]) - options is an object with these possible fields: name, unique, dropDups
	db.users.reIndex()
	db.users.find([query],[fields]) - query is an optional query filter. fields is optional set of fields to return.
	                                              e.g. db.users.find( {x:77} , {name:1, x:1} )
	db.users.find(...).count()
	db.users.find(...).limit(n)
	db.users.find(...).skip(n)
	db.users.find(...).sort(...)
	db.users.findOne([query])
	db.users.findAndModify( { update : ... , remove : bool [, query: {}, sort: {}, 'new': false] } )
	db.users.getDB() get DB object associated with collection
	db.users.getIndexes()
	db.users.group( { key : ..., initial: ..., reduce : ...[, cond: ...] } )
	db.users.mapReduce( mapFunction , reduceFunction , <optional params> )
	db.users.remove(query)
	db.users.renameCollection( newName , <dropTarget> ) renames the collection.
	db.users.runCommand( name , <options> ) runs a db command with the given name where the first param is the collection name
	db.users.save(obj)
	db.users.stats()
	db.users.storageSize() - includes free space allocated to this collection
	db.users.totalIndexSize() - size in bytes of all the indexes
	db.users.totalSize() - storage allocated for all data and indexes
	db.users.update(query, object[, upsert_bool, multi_bool])
	db.users.validate( <full> ) - SLOW
	db.users.getShardVersion() - only for use with sharding
