Description:
    Generate a new PIN to enable/disable your function

    ## In your js code, add this to validate if the user is allowed to access the function:
    import MatrixCheck from './common/MatrixCheck';
    if (MatrixCheck(currentUser.matrix, 'userLabel')) {
      // Enable your function
    }

    ## In your ruby code, add this to validate if the user is allowed to access the function:
    if user.matrix_check_by_name('userLabel')
      // Enable your function
    end

    ## In rails console, switch your function on:
    Matrice.find_by(name: 'userLabel').update_columns(enabled: true)

    ## In rails console, switch your function off:
    Matrice.find_by(name: 'userLabel').update_columns(enabled: false)


Example:
    rails generate matrix userLabel
    or
    rails generate matrix user_label

    This will create:
        db/migrate/20200825101133_matrice_user_label.rb
    and return the name:
    function name: [userLabel] created
