Creating GranuleCollectorFactory

Creating a GranuleCollectorFactory to abstract out creating granule
collectors, moving actual mosaic creation logic into granule collector,
eventually going to rename these classes to reflect their new
responsibilities. Had to make some inner classes static to accomplish
this.
Moving GranuleCollector to its own package + all the necessary modifier changes for that
Adding granule collector factory to raster layer response
Indexer is now initialized when ImageMosaic is initialized.
this was done so that we have access to its configuration while
reading the image mosaic.
A decent number of things shuffling around, in particular moving some
subclasses out of RasterLayerResponse to top level classes for clarity
(since these classes are now used outside of this class)
Added the correct test results image
Don't use default Operations object, instead create one with hints we may need.
Removed some unused code that was missed
Removed some unused imports
Fixed a test case with a fixed number and the size check in RasterLayerResponse to account for nulls in the list
Fixed an issue where indexer file wasn't getting initilized correctly

Reformatting the code in Eclipse

Renamed isHasAlpha and isDoTransparency to more sensible names

- Changed ReprojectingConfigHandler to properly respect sort order
- Relax requirement on property collectors in order to support collectors that don't need config
- Added some defaults to properties collectors and granulecollector when HETEROGENEOUS_CRS is true

- Rename coverageEnvelope to granuleEnvelope and make its access private

- Removing unused granuleCRS

- Rename old references to GranuleCollectors to SubmosaicProducers

- Move Mosaicker into its own compilation unit.

- Add another utility method to indexer utils for setting params on an Indexer
- Remove submosaic producer artifacts from GranuleCatalog and CatalogConfiguration bean, now moved to RasterManager

- Removed some debugging code that had been left in.

Simplified the sorting

Fixed a test that had been messed up by a mangled rebase
