function M = perform_vf_integration(vf, dt,T_list, options )

% perform_vf_integration - perform a time integration of the vf
%
%   M = perform_vf_integration(vf, dt, T_list, options );
%
%   real(M(i,j,t)) is the X location of the point (options.posx(i),options.posy(j))
%       at timestep T_list(t).
%
%   The vf is assumed to be sampled at locations [1,...,n]^2 unless posx and posy are given.
%
%   The integrator is a simple explicit euler, but it is very 
%   fast thanks to vectorization.
