Initial implementation of Dart Tooling Daemon server
This will contain the code for running the DTD server.
When this is fully funcitonal VSCode will be responsible for running the, and letting our other tools(i.e. DevTools) know which address it is running at.

+The server implementation for the Dart Tooling Daemon. This is meant to be run
+by our internal tooling and facilitates communication between our internal
+tools.
+
+# Running the sample
+
+## Running with the Dart SDK
+
+You can run the example with the [Dart SDK](https://dart.dev/get-dart)
+like this:
+
+```
+$ dart run bin/dtd_server.dart
+The Dart Tooling Daemon is listening on 0.0.0.0:8080
+```
+
+## Compiling the binary
+
+`dart compile exe bin/dtd_server.dart -o bin/dtd_server`
