* Initial stab at a trigger script for Jenkins mult-branch pipeline

* CHANGE_URL is not working, so disable for now

* CHANGE_AUTHOR not found either, disabling

* Disable some prints of vars that do not appear to be available

* Add in node block

* Correct the node-label expression

* Put Jenkins repo in a subdirectory and use the requested branch

* Fix groovy syntax error

* Call ngraph-unittest.groovy

* Corrected the branch name for cje-algo

* Now that the GitHub plugin is working, try restoring CHANGE_URL and CHANGE_AUTHOR

* Set an environment variable MB_PIPELINE_CHECKOUT, to trigger proper checkout command in runNgraphBuild()

* Try alternate load mechanism

* I've settled on using "load()" to directly run the code in ngraph-unittest.groovy, so remove vestigal loading of an ngraphUnitTest() function

* Change parameter assignments to be of the form params.var = 'new value'

* Try alternate method of setting parameter values for ngraph-unittest.groovy

* Try parameters-setting syntax from https://qa.nuxeo.org/jenkins/pipeline-syntax/globals#params

* Correct typo

* Try to work around parameter expansion issue

* Modify strategy for passing parameters and using MB Pipeline style checkouts, as per discussions with Nick

* Fixed calling syntax

* Simply call

* Remove prints

* Move CI to working from Jenkins cje-algo master branch
