A simple ValueConverter that can change visibility when a text value that is bound to it is null or empty

Readme.MD

#Using a ValueConverter to make a control visible when there is string content.

Sometimes it is useful to have a control completely disappear when it or another value has no text value. In this case, it is handy to be able to bind the control to the string value, and trigger a visibility change when it has not value. You can also achieve this by using a data trigger on a style.
