%   FIND_MIN() function
%
%   Finds the minima in a voltage trace V.
%_______________________________________________________________
%   Arguments:
%       V = vector of voltage values
%_______________________________________________________________
%   Returns:
%       H = vector of length(V), s.t.:
%           H(i) = V(i) if V(i) is a local minimum,
%           H(i) = 0 otherwise.
