%
%   Get the distances between points of two ldb's.
%
%   Syntax:
%   [pointLdb1,pointLdb2] = getDistance(ldb1,ldb2,buffer)
%
%   Input:
%   ldb1,ldb2 = the two ldb's to be used
%   buffer    = the maximum distance two set the position of points to
%               equal
%
%   Output:
%   pointLdb1, pointLdb2 = the indices of ldb's that are within the asked
%                          distance
