Feature: Language Server Protocol, Reference Support

[processing-bot]

Created by: Efratror

Description

Add a feature for supporting references to the LS

Expected Behavior

References are supported by the PDE (find usage). So it would be nice to have it for the server as well

Current Behavior

Only finding declarations is supported at the moment

Your Environment

• Processing version: 4.2
• Operating System and OS version: Windows 10
• Other information: Source includes PR [PR] LSP feature/declaration support - [merged] #678

Possible Causes / Solutions

• Add static function "searchReference" to the "pdeSymbolFinder" class
• Use it to find all references using the AST,
• Send (found) references back to the LS-client

I'm willing to implement this, please assignee me if you're ok with this idea.

@benfry could you please explain what I missed in my previous pr regarding the style sheet? I had read it before placing the pr but clearly I misunderstood some parts of it.

Thanks in advance

The main one was things like

if(optionalJavaOffset.isEmpty()){

which should read

if (optionalJavaOffset.isEmpty()) {

but I'd have to check if there were others. Perhaps it wasn't much?
