                <p>

                    Newly introduced interface <code>DependencyProjectProvider</code> is meant as less general replacement for <code>SubprojectProvider</code>

                    as it's explicitly declaring it's contract to be the project's dependency projects. Code using <code>SubprojectProvider</code> currently

                    should evaluate if <code>DependencyProjectProvider</code> contract suits their usage. Please note that <code>DependencyProjectProvider</code> is not

                    mandatory for project types to implement and if it's missing, <code>SubprojectProvider</code> should be used.

                </p>

                <p>

                    Implementation note: In Maven based projects, <code>SubprojectProvider</code> no longer returns project dependendencies and only returns submodules for 

                    projects with pom packaging. <code>DependencyProjectProvider</code> is now the one returning project dependencies as the list depends on currently opened project list.

                </p>

 * <b>Note:</b>Since 1.53, there is a more specifically defined variant <code>DependencyProjectProvider</code> that if defined in project provides a list of

 * projects the current project depends on. In some project types ( currently maven support) that is the preferred and supported way of getting project's dependency projects. 

 * The SubprojectProvider implementation is then used just to point to aggregator's module projects that are built together but have no direct dependencies on)
