DataModel (api 1.16.0 API)

```
@ProviderType
public interface DataModel
```
This interface is used for storing and managing data that represents the current configuration of, e.g. a ProgramNodeContribution or InstallationNodeContribution. Methods for adding, removing, retrieving and changing values in a dictionary are provided.

Setting a new value for a key already in use, will overwrite the current value with the new value. This happens regardless of the type of value (e.g. storing the value true under the key myBool and afterwards storing an Angle object under the same key will overwrite the value true with the provided Angle object). Setting a null value for a key, will remove the key and its value, if it exists, from the data model.

A URCap installation screen has an underlying DataModel object. That object is saved and loaded along with each PolyScope installation.

Similarly, each contributed program node instance has an underlying DataModel object. That object is saved and loaded along with the program where the node occurs. Undo/redo actions are supported for all modifications to the DataModel object in HTML-based program node contributions. Swing-based URCaps must use the UndoRedoManager to record the changes on the undo/redo stack.

When retrieving an object, both key and object type must match what was previously stored. This means that if a TCP object was stored using the key myAngle, then attempting to retrieve it using get(String key, Angle defaultValue) with the key myAngle will not return the stored value, since the types do not match. Instead the provided defaultValue will be returned.
