## Write tabular data to an ascii file.
##
## @var{data} is written to an ascii data file named @var{filename} with
## an optional @var{delimeter}. The delimeter may be any single
## character or
## @itemize
## @item "space" " " (default)
## @item "tab" "\t"
## @item "comma" ","
## @item "semi" ";"
## @item "bar" "|"
## @end itemize
##
## The @var{data} is written starting at cell (2,2) where the
## @var{varnames} are a char matrix or cell vector written to the first
## row (starting at (1,2)), and the @var{casenames} are a char matrix
## (or cell vector) written to the first column (starting at (2,1)).
