CreateHTMLTable:

--------------------------------------------------------------------------
   Creates an HTML table from x. x may be a two dimensional cell array or
   a matrix. If fileName is a string, it will open a file with the name
   fileName.html and write the matrix into the file. If instead you enter
   a file id it will write to the already open file. fString applies only
   to numbers. The default for fString is %12.4e.
