function KeepPos = GetPosition(BaseVector,CompareVector)
% GetPosition: Compares two vectors and determines the positions where the base vector
%              entries are unique.
%
% EXAMLPE: Suppose
%
%         BaseVector = [2 4 7 10]
%         CompareVector = [2 10]
%
% The function now returns [2 3] since those are the positions in BaseVector with unique elements.
%
% USAGE:
%
%       KeepPos = GetPosition(BaseVector,CompareVector)
%
% REQUIRED INPUT:  BaseVector (vector) of dimension 1xn
%
%                  CompareVector (vector) of dimension 1xm, with m<=n.
%
% REQUIRED OUTPUT: KeepPos (vector) of dimension 1x(n-m) with the positions of the
%                          elements in BaseVector that do not appear in CompareVector.
