Major Update:

- JSONparseCore:
  - Add initialisations values for class params
  - Add method AddBase() to dynamically change DataTree
  - Added Error messages
- DeviceCore:
  - Implement ValueTree (JSON tree)
    - Node are added as devices & params are created/added
    - Nodes (and path) are referenced on devices & params
    - Node values are updated as device params are updated
  - Added Persistence File (not yet complete)
  - Updated InitDevices() & InitDeviceParams()
    - Split into smaller methods: CopyTemplateParam() & InitDeviceParam()
    - Load Device definition or Parameter maps from files
    - Allow loading of nested parameter map files
    - Load Parameter as JSON tree, generate names/path dynamically
