function parts = strsplit(splitstr, str, option)
%STRSPLIT Split string into pieces.
%
%   STRSPLIT(SPLITSTR, STR, OPTION) splits the string STR at every occurrence
%   of SPLITSTR and returns the result as a cell array of strings.  By default,
%   SPLITSTR is not included in the output.
%
%   STRSPLIT(SPLITSTR, STR, OPTION) can be used to control how SPLITSTR is
%   included in the output.  If OPTION is 'include', SPLITSTR will be included
%   as a separate string.  If OPTION is 'append', SPLITSTR will be appended to
%   each output string, as if the input string was split at the position right
%   after the occurrence SPLITSTR.  If OPTION is 'omit', SPLITSTR will not be
%   included in the output.
