v0.3.0

This release adds support for additional API endpoints and continues to add more documentation.

• Shared links for files. Shared links can be created and modified for files.
• Collaborations endpoint. Collaborations can be created, retrieved, updated and removed.
• Add ProgressListener support for requests and responses. The progress of BoxAPIRequests and BoxAPIResponses can be monitored by providing a ProgressListener.
• Generic types were removed from Info classes. This makes working with resource info objects easier and less cumbersome.
• Javadoc and guide improvements. Add more documentation for existing classes without javadocs.
