Add: State for issue eupn#71

This initial commit contains the state of play immediately after
add the example crates:

- test-project
- test-procmacro-project

Other than setting up the workspace references no changes
to the example crates have been made.

The integration test harness has not yet been implemented.

+# `test-project`
+
+This is an example virtual-workspace that contains crates:
+
+- `wrkspc`
+- `wrkspc-dev`
+- `wrkspc-macro`
+- `wrkspc-test`
+
+Where each crate is:
+
+- `wrkspc`: A "Hello world" style library (for release as a crate).
+- `wrkspc-dev`: A "Hello world" style library for development (not for release).
+- `wrkspc-macro`: The `test-promacro-project` adjusted to fit into the workspace plugin-test harness.
+- `wrkspc-test`: The `test-project` adjusted to fit into the workspace plugin-test harness.
+
+Test harness for integration tests as plugins, is per the [Infinyon/Fluvio](https://www.infinyon.com/blog/2021/04/rust-custom-test-harness/) setup.
