/*
Tiddlers are an immutable dictionary of name:value pairs called fields. Values can be a string, an array
of strings, or a date.
Hardcoded in the system is the knowledge that the 'tags' field is a string array, and that the 'modified'
and 'created' fields are dates. All other fields are strings.
The Tiddler object exposes the following API
new Tiddler(fields) - create a Tiddler given a hashmap of field values
new Tiddler(tiddler,fields) - create a Tiddler from an existing tiddler with a hashmap of modified field values
Tiddler.fields - hashmap of tiddler fields
*/
