NAME
       integrate - integrate a function

DESCRIPTION
       Integrate a function over a domain by using a quadrature formulae.

SYNOPSYS
	template <class T, class M, class Function>
	T integrate (const geo_basic<T,M>& g, Function f, quadrature_option_type qopt)

EXAMPLE
	 Float f(const point& x);
	 ...
	 Float value = integrate (omega, f, quadrature_option);

	An optional argument specifies the quadrature formulae used
	for the computation of the integral.

IMPLEMENTATION
       template <class T, class M, class Function>
       T integrate (const geo_basic<T,M>& g, Function f, const quadrature_option_type& qopt)
       {
	   space_basic<T,M> Xh (g, "P0");
	   field_basic<T,M> int_K_f_dx = riesz (Xh, f, qopt);
	   return dot (1, int_K_f_dx);
       }
