Emacs ringing system: Diary format

Before I made it read standard SiRiL method files, the program read files in the following formats:

one based on the Ringing World Diary

Method: St. Clement's College Bob Minor
X
16
X
36
X
36
^
12

Single:
1234

Bob:
14

a hybrid between that and SiRiL

Method: St. Clement's College Bob Minor
&-16-36-36,+12

Single:
1234

Bob:
14

At your own risk, you could try a mixture of these in one file.

To use these formats, set the emacs variable ringing:always-use-method-library to nil. The program then expects to find these files in the directory ~/ringing/methods/ (or the directory named by the emacs variable place-notation:default-methods-directory), but it gives you a chance to tell it to look elsewhere as you start it.
