function [dv,foldi,be]=degamini(v)
%  [dv,foldi,be]=DEGAMINI(v)
%
% Inverse operation for GAMINI
%
% INPUT
%
% v       A vector with repeated entries (not necessarily sorted)
% 
% OUTPUT:
%
% dv      The same vector with all the repeats set to 1
% foldi   A same-dimensional vector with how many repeats there were
% be      A matrix with begin and end indices into the original vector
