How to reproduce

Try to save CultureInfo object using function Angara.Html.Save:

 Angara.Html.Save "culture.html" System.Globalization.CultureInfo.CurrentCulture 

Expected: The culture.html file produced that displays public properties of the CultureInfo instance; circular references can be shown as hyperlinks within the document.

Observed: The function Angara.Html.Save throws an exception StackOverflowException.

At least we should add the remark to the inline documentation of Angara.Html.Save.
