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
