/**
 * This interface narrows {@link NonCodeMembersContributor} to a closure executed inside particular method call at a gradle script.
 * <p/>
 * Example:
 * <b>build.gradle</b>
 * <pre>
 *   subprojects {
 *     repositories {
 *       mavenCentral()
 *     }
 *   }
 * </pre>
 * Here <code>'subprojects'</code> should be resolved at context of a global script; <code>'repositories'</code> in a context of
 * <code>'subprojects'</code> and <code>'mavenCentral'</code> in a context of <code>'repositories'</code>. Every such context
 * is expected to be backed by corresponding implementation of the current interface.
