{Parses a multi-valued string into its constituent fields.
 ExtractHTTPFields is a general utility to parse multi-valued HTTP header strings into separate substrings.
 *Separators is a set of characters that are used to separate individual values within the multi-valued string.
 *WhiteSpace is a set of characters that are to be ignored when parsing the string.
 *Content is the multi-valued string to be parsed.
 *Strings is the TStrings object that receives the individual values that are parsed from Content.
 *StripQuotes determines whether the surrounding quotes are removed from the resulting items. When StripQuotes is true, surrounding quotes are
  removed before substrings are added to Strings.
 Note:	Characters contained in Separators or WhiteSpace are treated as part of a value substring if the substring is surrounded by single
 or double quote marks. HTTP escape characters are converted using the HTTPDecode function.}
