[Feature Request]: handle xpath axis in the locator builder

[MohabMohie]

Be able to do this:

SHAFT.GUI.Locator.hasTagName("div").onAxisWith().followingSibling("div").hasText("uniqueText").build();

Logic should be simple, onAxisWith() should call a nested class that has all the supported axis methods, it should manually override the locator builder to use xpaths only, and should build a new locator object with that tag name.

I believe full recursion should be possible so that we can keep using axis elements infinitely and eventually build.
