> {{CSVFormat}} has two parameters to control how the leading and trailing spaces around values are handled, but the actual behavior depends on the value being enclosed in quotes or not.
> If the value is not enclosed in quotes, setting {{leading/trailingSpacesIgnored}} to {{true}} will left or right trim the value. For example with this input (using the default format):
> {code}a,  b  ,c{code}
> the second value will be equal to {{'b'}}.
> But if the value is enclosed into quotes, the value is no longer trimmed:
> {code}a," b ",c{code}
> this will give {{' b '}}.
> With quoted values the parser actually ignores the spaces between the delimiter and the quote. Thus with this input:
> {code}a, " b " ,c{code}
> The value returned is {{' b '}}.
> If {{leading/trailingSpacesIgnored}} is set to {{false}}, we get instead {{' " b " '}} which is consistent with RFC 4180.
