MultiTiddlerFiles allow multiple tiddlers to be concisely represented in a single text file.
The goals of this format are:
* To be easy to type and easy to read
* Optimised for single line strings
* To allow common fields or tags to be shared within groups of tiddlers
* To be simple to process with external tools
MultiTiddlerFiles have the extension `tids`. The file is structured as a block of shared fields followed by a blank line. The rest of the file is a sequence of comments and tiddlers. Tiddlers are specified by their title, followed by a colon, at least one space character, and then the rest of the line is the text field for the tiddler.
