puml includes

Utility project to include some common PlantUML files, that are used in the UML diagrams of the project

They have to be publicly available somewhere due that the "!include" directive of PlantUML doesn't work in Gitlab (see https://gitlab.com/gitlab-org/gitlab/-/issues/28847)

The UML files of EMERALD typically include several common files to define common graphical elements (arrows, colors, names, etc.). For example:

@startuml 

RCM Sequence Diagram
!include ..\roles.wsd
!include ..\color_pallette.wsd
