+ * "block" of dependencies which are pointers to other DependenciesBlock instances. For example
+ * when a Module has a CommonJs require statement, the DependencyBlock for the CommonJs module
+ * would be added as a dependency to the Module. DependenciesBlock is inherited by two types of classes:
+ * Module subclasses and AsyncDependenciesBlock subclasses. The only difference between the two is that
+ * AsyncDependenciesBlock subclasses are used for code-splitting (async boundary) and Module subclasses are not.
