[DMN Designer] Data-types: Grid: General

Different types of Expression (the grid-view) should support defining the input and output data-types. I am leaving implementation of this until the ability to use and define data-types at the graph-view is fully complete; as the scenarios required by this JIRA will re-use the same components.

Manual Acceptance test

• Specify some expression for both
• Open expression editor for first
• Rename the decision node in properties panel
  • Check << Back to XXX
  • Check Expression header cell
• Via navigation dock open second node expression
  • Check << Back to XXX
  • Check Expression header cell
• Rename the decision node in properties panel
  • Check << Back to XXX
  • Check Expression header cell

  • Check names are stored
