2    This defines the abstract vector component. These are patterned
3    after the Level-1 Blas, but with some additions that have proved
4    useful. These include routines to allocate and free vectors.
5 
6    Note that the routines that are normally thought of as returning a
7    value (e.g., dot, norm) return their value through an argument.
8    This allows these routines to be used with other datatype, such
9    as float and dcomplex.
10 
11    All vectors should be declared as a Vec. All vector routines begin
12    with Vec.
