Major changes from 1.4 to 1.5
=============================
Update version number for release.
Call shutdown on dealloc in MEMapViewController.
Refactor package loading system for supporting other map types.
Support map bounds and max level in map packages.
Add the Charlotte sectional as a package, low resolution.
Add virtual marker sample.
Added GL context management to play more nicely with other GL views.
Adding virtual vector map test, shows how to draw a grid.
Create a sample that demonstrates fancy marker images.
Add basic route planning example.
Modify Terrain rendering system to optinally flip textures when it renders them so we don't have to jump through hoops when we are generating data in the GDAL pipeline.
New terrain lighting system.
Port height profiling tests to AltusDemo from Mapp.
Put old resource manager in as option.
Add mult-view support.
Add test for multi-view system.
Updating default terrain color.
Port air traffic dynamic markers test from Mapp.
Support UIImage in MarkerTileLoadComplete for virtual marker maps.
Fix color mosaic test for new projection.
Add route with markers demo.
Add new sample, TileFactory, that demonstrates better default pattern of doing a tile provider that does thread management outside the work of generating a tile.
Make raster package tile provider  handle missing tiles at higher levels.
Refactor and simplify iOS marker API:
    Consolidate all marker passing functions to use MEMarker.
    Remove MEMarkerAnnotation, replace with MEMarker.
    Remove MEDynamicMarker, replace with MEMarker.
    Remove MEFastMarker, replace with MEMarker.
    Remove MEMarkerInfo, replace with MEMarker.
    Remove deprecated add/remove/update marker APIs that have been
    superceded by the Dynamic marker APIs.
Add support for hit testing to virtual marker system.
Modify virtual marker map renderer to add marker to marker frame.
Add MEVirtualMarkerMapInfo object for describing virtual marker maps.
Add AddVirtualMarkerMapUsingMap info function to MEMapViewController.
Add support for drawing polygons to dynamic vector map layers.

New samples:
Artistic/Asteroids: Demonstrates dynamic vector layers
VectorMarkers/AnimatedVectorCircle: Demonstrates vector circles and range rings
Utilities/TileFactory: Demonstrates how to properly create an asynchronous tile provider. Used in all of the raster maps and weather maps.
UserInteracton/MultiView: Demonstrates how to use multiple instances of MEMapView and how to chain them together.
Utilities/MovingObject2D: Demonstrates how to move an object around the globe over time.
Markers/Clustered/BusStops: Demonstrates how to use in-memory clustered marker maps with different image loading strategies. If you were using the now-removed FastMarker API, these serve as a guide for using the new consolidated system.
