  /**
   * Build the columns.
   *
   * The normal report class needs you to remember to do a few things that are often erratic
   *
   * 1) use a unique key for any field that might not be unique (e.g. start date, label)
   * - this class will prepend an alias to the key & set the 'name' if you don't set it yourself.
   *  You can suppress the alias with 'no_field_disambiguation' if transitioning existing reports. This
   *  means any saved filters / fields on saved report instances. This will mean that matching names from
   *  different tables may be ambigious, but it will smooth any code transition.
   * - note that it assumes the value being passed in is the actual table field name
   *
   * 2) set the field & set it to no display if you don't want the field but you might want to use the field in other
   * contexts - the code looks up the fields array for data - so it both defines the field spec & the fields you want to show
   *
   * 3) this function also sets the 'metadata' array - the extended report class now uses this in place
   *  of the fields array to reduce the issues caused when metadata is needed but 'fields' are not defined. Code in
   *  the core classes can start to move towards that.
