NullPointerException when no IconDataProvider implementation specified

[GoogleCodeExporter]

Finally, got some time to try Maps Extensions for my app. Migration went 
smooth, although docs are scarce (and i can probably be considered GMaps power 
user, having thus a competitive advantage;-).

One thing that is probably worth improving is to implement some default cluster 
icons.

What i intuitively did (after updating imports) was to add this line to my code:

  googleMap.setClustering(new ClusteringSettings().addMarkersDynamically(true));

After that my app went bust:

Sure, it's trivial to grab DemoIconProvider implementation along with some 
resources from sample project, but it'd be nice to have it out of the box.

Hello Taras,

The first thing to change is probably the exception that is being thrown, which 
says almost nothing about the reason. Bad, bad.

I also think it would be beneficial to have some default implementation.

Added DefaultClusterOptionsProvider which is used when no provider is set
