Have the ability to add Spreadsheet Headings

[ricardosaracino]

It would be great to have the ability to add Spreadsheet Headings to give the user supplemental information.

I achieved the below by wrapping all the columns in a column group so maybe you could reuse that internal logic somehow to add the spreadsheet headings (just an idea).

  <igx-column-group header="{{ fundName }}">

    <igx-column-group header="{{ 'LABELS.' + data.currentReport.reportName | translate }}">

      <igx-column-group header="Start Date: 2012 - End Date: 2013">

        <igx-column [pinned]="true"  [hidden]="true" [resizable]="true" [sortable]="true" dataType="string" field="label"
                    header="{{ 'LABELS.CLASS' | translate }}" minWidth="220px">
        </igx-column>
