Changed DEFAULT_ZOOM_LEVELS to maxZoomLevel, DEFAULT_FULL_EXTENT to maxExtent,

Browse Source 
and RESOLUTION_AT_ZOOM_LEVEL_0 to maxResolution. These values are no longer constants,
but have (thanks to JavaScript object prototyping) sensible defaults.

These defaults can now be overridden by passing a hash as the second argument of
the Map constructor.

Added tests to verify.
