Add same column twice (material-ui data grid)

[Jozef Slezak]

Goal: generate unique columns id/field for the same column

Background: MaterialUI Data Grid -field is the only required property since it's the column identifier.

Requirements

• check if the column id (field) is allready present (for example { field: "name")
  valueGetter
• use { field: "name", valueGetter if the entity does not contain unique columne id
• use suffix: 2, 3, 4 (for example { field: "name"...) for column id (field) if the field is allready present in columns
• ability to define columnId (use case: user could define "fullName" concantenated from first name and last name)

API

• extend existing API addColumn parameters options with new optional columnId
