it's necessary to detect compatibility among meta-model versions integrated within the different versions.

a later phase is to provide data migration options among major version changes.

R4E core was updated to assign default values and application level version values for three sub models i.e. Group, Review, RuleSet.
An api was introduced to resolve detect compatibility of already serialised models against the current version of the application. 
  R4E core throws and exception when a serialised version is ahead of the current application
  R4E UI detects if the serialized version is below the version supported by the application if so the user is prompted to decide on converting the model to the same level as the application or to open it in Read Only mode (to prevent overriding a format that may prevent other users from opening it).
