XUnit_Conditional_Fact (nuget): An xunit attribute to provide skip functionality to any xunit test discoverer.  You specify the FactAttribute type ( FactAttribute and TheoryAttribute have their own helper attributes FactConditional and TheoryConditional )  that you may potentially want to skip then apply ITestCondition attributes.  If a single attribute reports a non null SkipReason the test is skipped.  If the test is not skipped then the specified discoverer will run.  You can provide your own skip logic if the default is not sufficient.
