function casewrite(strmat,filename)
%CASEWRITE Writes casenames from a string matrix to a file.
%   CASEWRITE(STRMAT,FILENAME) writes a list of names to a file, one per line. 
%   FILENAME is the complete path to the desired file. If FILENAME does not
%   include directory information, the file will appear in the current directory.
%
%   CASEWRITE with just one input displays the File Open dialog box allowing
%   interactive naming of the file.
