Detailed Description

Add basic arithmetic support to vector.

Let u and v be two vectos and r be a scalar. This file defines the following operators:

• u += v
• -v
• v *= r
• inner_product<typename> (u, v)

Note:

The template can `recursively' apply itself to vectors of vectors, such as two matrices of real numbers could add up (if they have the same size).

Warning:

u, v, and r can have different base types. For example, if u is a double vector and v an integer vector. When an inappropriate coercion happens, the compiler may complain (with gcc, turn options -Wconversion or -Wall on).
