/** \brief Node <tt>VectorSpaceBase</tt> subclass that provides default
 * implementations for many functions using a default multi-vectors
 * implementation.
 *
 * <b>Notes to Subclass Developers</b>
 *
 * Because of the default multi-vector implementation used in this node
 * subclasses, a concrete subclass is only required to override four
 * functions: <tt>dim()</tt>, <tt>isCompatible()</tt>, <tt>createMember()</tt>
 * and <tt>smallVecSpcFcty()</tt>.  Note that implementing the
 * <tt>createMember()</tt> method also entails defining a concrete
 * <tt>VectorBase</tt> subclass and defining <tt>smallVecSpcFcty()</tt>
 * entails defining a concrete <tt>VectorSpaceFactoryBase</tt> subclass.
 *
 * If a subclass can support specialized multi-vectors, then the
 * <tt>createMembers()</tt> function should be overridden as well.  Note that
 * implementing <tt>createMembers()</tt> also entails defining a concrete
 * <tt>MultiVectorBase</tt> subclass.
