function EDB1editpathlist(edpathsfile,useedges,symmetricedges,pathstokeep)
% EDB1editpathlist - Does some semi-automatic editing of an edpathsfile.
% A vector, 'multfactors' is introduced, which will boost or
% keep or switch off paths in the list of paths.
%
% Input parameters:
%   edpathsfile     An edpaths file that should be modified.
%   useedges        (optional) A list of edges that should be used. All
%                   paths that contain an edge which is not this edge will
%                   be switched off.
%   symmetricedges  (optional) A matrix of edge pairs that are symmetrical
%                   around a symmetry plane. If, e.g., edges 2 and 3 are symmetric around the
%                   source/receiver plane, then symmetricedges = [2 3]. Several pairs are
%                   possible; symmetricedges = [2 3;7 8;9 12];
%   pathstokeep     (optional) A matrix of specific diffraction paths to
%                   keep.
