[Research] OUI usage audit in the tile_map plugin

[BSFishy]

Audit

Looking in the tile_map plugin, there are only 2 Sass files. They are src/plugins/tile_map/public/_tile_map.scss and src/plugins/tile_map/public/index.scss. index.scss just imports _tile_map.scss.

_tile_map.scss defines 2 classes:

// SASSTODO: Does this selector exist today?
.tilemap {
  margin-bottom: 6px;
  border: $euiBorderThin;
  position: relative;
}

/**
* 1. Visualizations have some padding by default but tilemaps look nice flush against the edge to maximize viewing
* space.
*/
// SASSTODO: Does this selector exist today?
.tile_map {
  padding: 0; /* 1. */
}

Neither of these classes are actually used anywhere. Commenting them out doesn't change the visual appearance of the visualization at all. Additionally, the className prop isn't used anywhere in the tile_map plugin.

Conclusion

Both of the Sass files can be removed safely.
