function cas = wstextread(sFileName, cDlm)
%WSTEXTREAD puts a delimited file in a cell array of strings.
%   CAS = WSTEXTREAD(SFILENAME, CDLM) returns the contents of
%   file SFILENAME delimited with the delimiter character CDLM
%   in CAS, a cell array of strings.
%   CAS = WSTEXTREAD(SFILENAME) uses the tab character as the 
%   default delimiter.
