Positioning system

Back End

Proposals

Some fragments of how the architecture could change in the future, and why (or why not) they might be a good idea.

• Reorganize client source with lerna and typescript projects #76

• Add DiagnosticsManager, refactor DiagnosticPanel #176

• Multiple sources of LSP messages on frontend and backend #184

• Formalize and extend language transclusion #191
