[DMN Designer]: Decision Table: Automatically create input columns for each InputData element

mmortari@redhat.com suggested it advantageous to create input columns for each InputData element linked to the Decision containing the DecisionTable expression. For example, if a Decision has 2 InputData nodes of simple data-types then two columns should be created. If a Decision has 1 InputData node of complex data-type that consists of 3 elements then 3 columns should be created.

• For simple data types the input column names should correspond exactly to InputData elements.
• For complex data types, we should use dot notation, e.g. Person.name, Person.salary ...
