[seanpearsonuk]

Creating a simple PyFluent REST Settings interface

Step 1 (exploration)

my-rest-client ---> fluent REST API for solver settings

my-rest-client: BASIC PYTHON

Step 2

my-simple-launcher ---> my-session-class ---> flobject ---> my-rest-proxy ---> my-rest-client

my-simple-launcher: TRIVIAL
my-session-class: SMALL
flobject: UNCHANGED
my-rest-proxy: SUBS FOR gRPC/IN-PROCESS
