Steve Karg 810a2f93de Feature/write property type check refactor (#182) 
* refactor write-property tag check

* modify ports objects to use write-property tag check API

* modify example objects to use write-property tag check API

* Fix object unit test builds

* Fix and run unit ztests via CMake

* Enable unit testing on Travis CI
