Change expression help from free form html files to structured json A new script then parses these json help files into the html help contents, in a standardised manner. Previously, the function help was a bunch of different formats and structures. Now, a custom stylesheet can be applied (and later tweaked!) to format these help. Eg, this commit colors variables and function names in the syntax section for greater readability. 2015-06-11 12:02:27 +10:00			`{`
