/**
* The social activity interpreter local service. Activity interpreters are
* classes responsible for translating activity records into human readable
* form. This service holds a list of interpreters and provides methods to add
* or remove items from this list.
*
*
* Activity interpreters use the language files to get text fragments based on
* the activity's type and the type of asset on which the activity was done.
* Interpreters are created for specific asset types and are only capable of
* translating activities done on assets of those types. As an example, there is
* an interpreter BlogsActivityInterpreter that can only translate activity
* records for blog entries.
