Mapstraction - Apr 2012 - Constructor default settings (Andrew Kirwin)

Thanks Andrew (Turner),

That does sound like it would work, but no joy for me
(example<http://jsfiddle.net/amk221/mh4Vb/1/>
).

I''d previously notice Nestoria use this {defaultLayer:false} too, but I
can''t figure out how its working. As far as I can tell defaultLayer is
not
actually in the source at all. Should I be altering applyOptions() for
leaflet in order to handle this?

Cheers,
Andrew Kirwin
