general architecture java code structure

What this boils down to is: We have three "kinds" of code/modules in ./clc/modules:

1. Library: this code is at the root of the dependency tree and can't have forward references to module kind #2.
2. Component-common: this code other components or parts of the system w/ the bits needed to use the service.
3. Component: this code provides the implementation of the service or component.

Library Code

Service Code

Service/component code is made up of two parts: (e.g., handle registration/configuration, send messages, etc.)

1. modules/service-common directory: client code, these are types which must be shared and available to interact with, configure, reference the service; e.g., message types, component ids, service registration handling. these should never include service implementation code, nor should there be a build order between these directories (i.e., there shouldn't be dependencies between the
2. modules/service directory: this code does whatever the service does
