Update Summa-Actors to CAF version 1.0.0

[KyleKlenk]

With the most recent updates to CAF, the interface for actors has changed from version 0.18.6 in which Summa-Actors is currently based on.

We need to update the actor implementations in Summa-Actors to reflect the changes. Currently the core functionality should be working in the branch: caf_v1_changes

Core functionality includes:

• Asynchronous mode, where GRUs run independently from each other.
• Data-Assimilation Mode, where all GRUs must run a timestep before moving onto the next. The distributed features do not work and this is for a single node.

Update on status:

• V1 version of CAF has been implemented for the use in the development branch.
  • The only feature missing is the kitchen-sink cluster functionality but that is being saved for a later point and was not used by anyone currently
