Hi,
I would like to contribute a new XUnitHelper for version 2.
The name of the helper would be obviously XUnit2Helper.
After poking around with the v2 of xunit i found out that there are breaking changes in XUnitHelper like the argument are now passed in with "-" instead of "/".
Some arguments are new, some went away, new functionality has been added etc etc (parallel support, appveyor support.
There is really no point to modify the existing one to be forward and backward compatible since at some point there will be v3 of xunit.
Any suggestions?
