class ObjectType
******************
Each object type is represented by a subclass of this class.
When such a subclass is instantiated, the ObjectType that it represents (the complete objecttype, including variables and their properties, methods and references)
is constructed in the address space.

This object has methods to retrieve the instance declarations of the
variables of the object type (return type: VariableType) 

class Object
******************
Each object is implemented by a subclass of this class.
When such a subclass is instantiated, the Object that it represents is
constructed in the address space.

This object has methods to retrieve the variables of the 
object (return type: Variable)

class VariableType
******************
Each VariableType (instance declaration) is represented by a subclass of this class.
When such a subclass is instantiated, the VariableType (instance declaration) that it represents
is constructed in the address space.

class Variable
******************
Each Variable is represented by a subclass of this class.
When such a subclass is instantiated, the Variable that it represents
is constructed in the address space.


Example of how it should work
*******************************
Say we have two classes: TemperatureSensor, which derives from Object and TemperatureSensorType, which derives from ObjectType.
When we instantiate TemperatureSensor the following happens:

1. If necesarry, create the TemperatureSensorType in the address space by instantiating TemperatureSensorType class.
2. Create all nodes and references in address space to get a complete TemperatureSensor Object.

How it will work (for now)
***************************************
The TemperatureSensor has a variable of AnalogItemType, which is already present in the address space.
It is put in the address space by another mechanism than described above (in the freeOpcUa lib itself), so there are no C++ classes
representing these nodes. For now we will just refrain from using the *Type classes and just
create the typenodes by hand in the constructor of the TemperatureSensor class.

// todo : write some thoughts about replacing the currently used mechanism to populate standard address space
