+/**
+ * A build context that matches a mavenproject to a given tasksegment, and the session to be used.
+ * <p/>
+ * A note to the reader;
+ * <p/>
+ * There are several issues/discussions regarding how "aggregator" plugins should be handled.
+ * Read for instance http://docs.codehaus.org/display/MAVEN/Deterministic+Lifecycle+Planning
+ * <p/>
+ * In their current implementation they are "bolted" onto the lifecycle by separating them
+ * into TaskSegments. This class represents the execution context of one such task segment.
+ * <p/>
+ * Wise voices have suggested that maybe aggregators shouldn't be bound to the ordinary
+ * lifecycle at all, in which case we wouldn't be needing this class at all ( and
+ * ProjectBuildList.getByTaskSegments). Or maybe they should be introduced in the calculation
+ * of the execution plan instead, which seems much nicer.
+ * <p/>
+ * Additionally this class contains a clone of the MavenSession, which is *only* needed
+ * because it has as notion of a "current" project.
+ *
+ * @since 3.0
