This is a simple start to a data source for accessing data in JSON and JSONJ files. This first version reads only JSONJ files, where an array of JSONArrays or JSONObjects can be read to retrieve data. A future version of this will allow reading data from a single JSONObject spanning multiple lines. Expected features:

- NEST thermostats appearently have extra quotes, and this needs to be investigated and supported
- multi-line JSONObjects and JSONArrays will be supported, looking for the terminal character '}' or ']' at the end of a line.
- support for dependencies (as with ASCII data) { 'time':'2025-03-05T07:34', 'temperature':37.0, 'windspeed':4.5 }
- support for units controls similar to ASCII table, so that units and labels can be asserted
- access to embedded tags with a.b.c { 'a':{'b':{'c':42 } } }
