## Read tabular data from an ascii file.
##
## @var{data} is read from 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 read starting at cell (2,2) where the
## @var{varnames} form a char matrix from the first row (starting at
## (1,2)) vertically concatenated, and the @var{casenames} form a char
## matrix read from the first column (starting at (2,1)) vertically
## concatenated.
