Detailed Description
The Vector class.This is a subvector that also allocates storage automatically, and deallocates it when it is destroyed. We take all the functionality from VectorView. Additionally defined in this class are:
1. Constructors and destructors (allocating memory). 2. Assignment operator from scalar. 3. Resize function.
It seems that we need no assignment operator from VectorView or Vector, because the one of VectorView is used.

Constructor setting size and filling with constant value.

Constructor filling with values.
Examples:
Vector v(1,5,1); // 1, 2, 3, 4, 5 Vector v(1,5,.5); // 1, 1.5, 2, 2.5, 3 Vector v(5,5,-1); // 5, 4, 3, 2, 1

Copy constructor from VectorView.
This automatically sets the size and copies the data. The vector created will have start zero and stride 1, independent on how these parameters are set for the original. So, what is copied is the data, not the shape of the selection.

| Vector::Vector | ( | const Vector & | v | ) | [inline] |
Copy constructor from Vector.
This is important to override the automatically generated shallow constructor. We want deep copies!

| Vector::~Vector | ( | ) | [inline] |
Destructor for Vector.
This is important, since Vector uses new to allocate storage.

Assignment from another Vector.
Important to avoid segmentation fault for x = Vector(n);
Reimplemented from VectorView.

Assignment operator from Array<Numeric>.
This copies the data from a Array<Numeric> to this VectorView. Dimensions must agree! Resizing would destroy the selection that we might have done in this VectorView by setting its range.
Array<Numeric> can be useful to collect things in, because there is a .push_back method for it. Then, after collecting we usually have to transfer the content to a Vector. With this assignment operator that's easy.
Assignment operators are not inherited, so we have to make an explicit call to:
VectorView VectorView::operator=(const Array<Numeric>& v)
here.

Assignment operator from scalar.
Assignment operators are not inherited.

| void Vector::resize | ( | Index | n | ) | [inline] |
Assignment operator from VectorView.
Assignment operators are not inherited. Resize function. If the size is already correct this function does nothing. All data is lost after resizing! The new Vector is not initialized, so it will contain random values.
