Support rendering tracks on Map tab

This should help identifying paths instead of isolate points of tracks/routes.

The current parser extract track points from GPX or KML as individual items, as they can have timestamps or other metadata associated. The track itself, within the file, is also extracted as a subitem of the file.
So we could identify track items as such, and plot the lines when selected. Also, when a item of this track is clicked, when can identify if it have a track as the immediate parent, and plot the lines.

Is there already implemented method on API to:

• get the parent IItemId of a specific Item?
• get the children IItemId of a specific Item?

Or should I create lucene querys to achieve this results?

1. If I remember you can get the parent ID then, using IIPEDSource, get the corresponding IItem
2. For this one I think a query search should be done

The track are being correctly parsed and shown. But now the navigation buttons can be confusing. May it follow the track order or the table sort order (original navigation behaviour).

Hi @patrickdalla. I never thought those buttons a must, since user can already navigate through items using the (sorted) table and the selection is propagated to the map, maybe when it was implemented at first the panels were not detachable.

So I think we can change the behavior to follow the track order when the item is part of a track, and maybe update the button labels to try to avoid confusion with old behavior. When the item is not part of some track, maybe those button could be disabled.
