Implement Document Highlights Request

[AnHeuermann]

Description

Document Highlights Request

The document highlight request is sent from the client to the server to resolve document highlights for a given text document position. For programming languages this usually highlights all references to the symbol scoped to this file. However, we kept ‘textDocument/documentHighlight’ and ‘textDocument/references’ separate requests since the first one is allowed to be more fuzzy. Symbol matches usually have a DocumentHighlightKind of Read or Write whereas fuzzy or textual matches use Text as the kind.

Desired features

• Highlight all locations where the same class shows up in the current scope.
• Server tests.
• Client end to end tests.

Examples

Check Modelica.Blocks.Examples.PID_Controller from the MSL. Highlighting PI should highlight all locations of PI inside the model.
