Paul, would you like to code review this? Sort of something you (and others) have requested.

The code is in lp:~chris-rogers/maus/devel/

Nb: I had a query that I wasn't sure about, which needs a perspective from user. We have a common "run control" thing like the old datacards, I've been trying to make sure everyone uses the common datacards stuff for controlling their code. For things like this, that are pretty much stand alone applications, I wasn't sure whether it would be better to have a few command line arguments defined in the code (as I've done here).

• In the first instance, we get a common interface to all executables but there are hundreds of control parameters that are not relevant to the application.
• In the second instance, we get some executables that have a completely different interface, that may jar with the rest of the code - especially if they start duplicating existing run control variables.

Thoughts, comments appreciated...

Done - bin/utilities/json_browser.py
