// Unserialize (to) form plugin
// Version 1.0.2
// Copyright (C) 2010-2011 Christopher Thielen
// Dual-licensed under GPLv2 and the MIT open source licenses

// Notes: Will recurse fieldsets and p tags as they are commonly used in forms.

// Usage: var s = $("form").serialize(); // save form settings
//        $("form").unserializeForm(s);  // restore form settings




// See ChangeLog at end of file for history.
