 The nsIFormHistory object is a service which holds a set of name/value
 pairs.  The names correspond to form field names, and the values correspond
 to values the user has submitted.  So, several values may exist for a single
 name.

 Note: this interface provides no means to access stored values.
 Stored values are used by the FormFillController to generate
 autocomplete matches.
