OneDimMultiFunctionAdapter class to wrap a multidimensional function in one dimensional one.
Given a f(x1,x2,x3,....xn) transforms in a f( x_i) given the coordinate intex i and the vector x[] of the coordinates. It provides the possibility to copy and own the data array of the coordinates or to maintain internally a pointer to an external array for being more efficient. In this last case the user must garantee the life of the given passed pointer

The coordinate cached vector is created inside and eventually the values must be passed later with the SetX which will copy them
