Summary

The client is going through their Lightning Migration.  There are a number of Buttons on their current classic page which are actually formula fields that call Apex.  While some of these buttons can be rebuilt using Actions, we want all of the buttons to look the same, so they all will need to be rebuilt using custom lightning buttons which require development.  Apttus has created some Lightning Buttons, but the Controller is within the Managed Package, and this is where the filter logic lives for showing/hiding buttons.  Therefore, we need to create our own Lightning Buttons so that we can manage and insert our custom filtering logic into the controller.  In addition, two of the buttons were custom built by Statera and those need to be built and included in the collection of buttons.
