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 } } }
