Initial version of the debugger - currently compiled by StateTreeModule and StateTreeEditorModule using WITH_STATETREE_DEBUGGER - currently not exposed to UI by StateTree settings 'bUseDebugger' - in this version only one instance per asset can be debugged - using Trace services to read events generated by statetree instances. - can connect to any traces (Editor, Client, Server) as long as the compiled statetree matches #rb mieszko.zielinski #preflight 641088a30e1f02786b509663 [CL 24639409 by yoan stamant in ue5-main branch]
