[ANN] XPath moved to GitHub

Hi,

the STHub -> PharoExtras project "XPath"

was now moved from http://smalltalkhub.com/#!/~PharoExtras/XPath to
https://github.com/pharo-contributions/XML-XPath including the FULL HISTORY

The old STHub repo was marked as obsolete - but is linking to the new one. I've also
setup an CI job: https://travis-ci.org/pharo-contributions/XML-XPath
which is green for Pharo 7. Some cleanups, class comments and docu was applied as you can
see from commit history.

The new version is tagged in git as version 2.2.0 (with a moveable tag 2.2.x in case further
hotfixes are required).

You can load using

    Metacello new
        baseline: 'XPath';
        repository: 'github://pharo-contributions/XML-XPath/src';
        load.


or from catalog in Pharo 7 or 8.

Attached is current dependency graph.

More to come soon ...

Bye
T.
