Easier / better documented configuration of accuracy

[trondtynnol]

The help page for accuracy tells me I can pass options to it via a json file:

-c <config>             Provide JSON config file to override test defaults

However, to find out what this file should contain, I had to delve into the source code and try and fail. Documentation for how this json file should look would be much appreciated.

Alternatively, getting to pass options directly from the command line would be just as useful, in my case especially for --no-case-handling.
