%>  \brief
%>  Return a list of objects of class [pm.sampling.FileContentsProgress](@ref FileContentsProgress)
%>  containing the content(s) of the ParaMonte simulation output progress
%>  file(s) whose path(s) match the specified input ``pattern`` or the
%>  simulation specification ``sampler.spec.outputFileName``.<br>
%>
%>  \warning
%>  This method is to be only used for post-processing of the output
%>  progress file(s) of an already finished simulation. Although possible,
%>  this method is NOT meant to be called by all processes
%>  in MPI-parallel simulations.<br>
%>
%>  \param[in]  self    :   The input parent object of class [pm.sampling.Sampler](@ref Sampler)
%>                          which is **implicitly** passed to this dynamic method (not by the user).<br>
%>  \param[in]  pattern :   The input scalar MATLAB string containing the pattern matching
%>                          the desired progress file(s) whose contents is to be read.<br>
%>                          The specified ``pattern`` only needs to partially identify
%>                          the name of the simulation to which the progress file belongs.<br>
%>                          For example, specifying ``"./mydir/mysim"`` as input will
%>                          lead to a search for file(s) beginning with "mysim" and
%>                          ending with ``"_progress.txt"`` inside the directory ``"./mydir/"``.<br>
%>                          If there are multiple files matching in the input ``pattern``,
%>                          then all such files will be read and returned as elements of a list.<br>
%>                          If the specified pattern is a valid existing URL, the file will be
%>                          downloaded as a temporary file to the local system, its contents
%>                          shall be parsed and the file will be subsequently removed.<br>
%>                          If the input ``pattern`` is empty, then the method will search
%>                          for any possible candidate files with the appropriate suffix
%>                          in the current working directory.<br>
%>                          (**optional**, default = ``sampler.spec.outputFileName`` or ``"./"``)
%>  \param[in]  sep     :   The input MATLAB string containing the field separator used in the file(s).<br>
%>                          (**optional**, default = ``sampler.spec.outputSeparator`` or automatically inferred.)
%>
%>  \return
%>  ``progressList``    :   The output MATLAB cell array of objects
%>                          of class [pm.sampling.FileContentsProgress](@ref FileContentsProgress),
%>                          each of which corresponds to the contents
%>                          of a unique progress file.<br>
