Determine visibility for implementating classes

[GoogleCodeExporter]

Determine if visibility should be reduced for "catalog" implementations (except 
for factory methods). For example, Braillo200Embosser has a public constructor, 
but should really only be called by its Provider. Therefore, package visibility 
should suffice.

Most of this should be resolved in the process of making braille utils OSGi 
compatible.
