CDK-177: Add View#delete.
update morphlines to use Solr 4.6
CDK-177: Rename View#delete to View#deleteAll.

This is less confusing when working with the entire Dataset as a View:
  events.delete(); // does this delete the Dataset? (no)
  events.deleteAll(); // clearly, deletes all records
Upgraded cdk-morphlines-solr-core from solr-4.4 to solr-4.6
Upgraded cdk-morphlines-solr-core from solr-4.4 to solr-4.6
CDK-177: Add FS deleteAll, finish tests.

This implements FileSystemView#deleteAll and finishes the FS tests. For
the getCoveringPartitions tests, it was necessary to compare FS views so
hashCode and equals methods have been added to AbstractRangeView and
MarkerRange. The AbstractRangeView implementations use the instance
class, so subclasses do not need to override them.
CDK-177: Rename View#in to View#of.

This commit renames View#in to View#of to avoid confusion with "in" as a
set-inclusion operation.
CDK-177. Add getters to Boundary SPI class.
CDK-177. Implement View interface for HBase.
Removed the DataAccessor class which was responsible for allowing users to do random access
gets and puts on a DataSet. I've created a new RandomAccessDataset interface that datasets
which should allow random access should inherit from. This replaces the functionality
DataAccessor provided.

The DaoView Reader implementation now correctly respects the inclusive/exclusive parameters
of a scan. This required adding inclusive boolean params to the Dao getScanner method.

The DaoView Writer implementation will restrict writes of entities to those who's keys
are within the view range.
Moving classes in the cdk-data-hbase module to packages that make more sense now that
the DAO classes are no longer going to be considered the public interface.
This is a combination of 2 commits.

Added a new RandomAccessDatasetRepository interface that is a sub interface of
DatasetRepository, but overrides load, create, and update to return the
RandomAccessDataset type instead.

Created two new static methods on DatasetRepositories called openRandomAcces,
which return a RandomAccessDatasetRepsotory.

Added more thorough tests for the different range combinations in the
DaoViewTest test class.
