Used requests where it made sense in the actors. This is where the HRU
would send a message then wait for a response anyway. Instead of defining
messages for these cases we use request.

Removed the reading of json variables that were writing to csv.

Added a debug mode for kinsol.

Added functionality for the job actor to record the stats of GRU actors
When the simulation is finished these stats are passed to the
file access actor where they are written to netcdf

Can get 1 HRU managed by the file access actor. An HRU will wait until it is told it can write again.

Got the clients communicating together.

removed dependency in batch class where the batch was provided a client. Now a client only contains the batch and not vice versa

Having more subroutines makes it more obvious how to break the calls down for the file_access_actor

Added threshold and heartbeat interval as parameters that are passed into summa through json

Client can be sent a heartbeat and then send  a message back to the server

 - This allows parent actors to have info for recovery and for the information to not have to be read from a file in the case we are in a distributed situation

 - also added better error message for read_attribute.f90

Implemented a function that prints the functions to stdout for verification

Moved the definition of the settings functions to their own file

adjusted the makefile to include the new settings_functions
