SVectorBase with prev/next pointers.
The management of the SVectorBases is implemented by a DataSet<DLPSV>, the keys used externally are DataKeys.
The management of nonzeros is done by a Real linked list IdList<DLPSV>, where the SVectorBases are kept in the order in which their indices occurr in the Array. The SVectorBases are kept without holes: If one is removed or moved to the end, the SVectorBase preceeding it obtains the space for all the nonzeros that previously belonged to the (re-)moved one. However, the nonzeros in use are uneffected by this.
