csv:to-file parsing bug

[jbintz]

If item 0 of the list "row" element is a negative number, the number is written as a string.

observer> csv:to-file "myfile.csv" [[1 "two" 3] [-4 -5]]

will result in a file myfile.csv containing:

1,two,3
"-4",-5

Thanks for reportering! However, CSV fields don't actually have types. Quotes are only used to keep a field together (in case it has , and a newline in it); they don't actually indicate that something is a string. If you open the file in Excel or re-import into NetLogo, the field is correctly interpreted as a number.
