Create JSON Objects and Arrays by SQL

The related package avoids adding %JSONAdaptor to each class but uses  instead   
SQL functions JSON_OBJECT() to create my JSON objects. With this approach, you can   
add JSON to any class - even deployed ones - without any need for change or recompiling.

The trigger was the Export of M:N relationships  as JSON  objects or arrays.

The typical structure of the export is  

{ M-element : {M-object},
   related-N-elements:
   [
     {N-element}, 
    {N-element},
    {N-element}
   ]
}
