function Result=idGetListOfOrbitsWithNaN(Directory, CoreFileName, GetAllFileNames)
% Written by F. Briquez 03/11/2011
% CoreFileName should contain an '*' character. If not, the '*' character
% is added at the end of CoreFileName, assuming the constant part of the
% name is its begining.
% Prints names of .mat files in which X or Z orbits contain at least one NaN
% GetAllFileNames=1 => reminds also the name of a file not containing NaN
