distributed vector

# Description

This vector class supports both the `sequential` and the `distributed` memory model. In addition, standard linear algebra is supported.

# Example

        vec<double> x (100, 3.14);
        vec<double> y (100, 6.28);
        vec<double> z = 2.5*x + y;
        dout << x << endl;

# Implementation

This documentation has been generated from file linalg/lib/vec.h

The `vec` class is a template class with both the floating type and the memory model as parameters. The implementation bases on the `disarray` container.

template <class T, class M = rheo_default_memory_model>
class vec : public disarray<T, M> {
