Detailed Description

template<class Scalar>
class Playa::Vector< Scalar >

User-level vector class.

Vector creation

Ordinarily, you will never construct a Vector directly from a derived type. Rather, the createMember() method of VectorSpace is used to build a vector of the appropriate type, for example, 

 VectorType<double> vecType = new EpetraVectorType();
 int dimension = 100;
 VectorSpace<double> space = vecType.createSpace(dimension);
 Vector<double> x = space.createMember();
 Vector<double> y = space.createMember();

This hides from you all the ugly details of creating a particular concrete type.

You will frequently create an empty vector to be filled in later, for example, 

 Vector<double> y;

Note that this vector isn't just empty, it's null. Not only does it have no values assigned, it does not have a concrete type. An call a method on a null vector will result in an error. What you <it>can</it> do with a null vector is
