Gem Update

[Jimmy Z]

I just committed changes adding "combine" and reading multiple persons
in a single request.

Next on the roadmap:
1. Better error handling - define and implement library-specific
Exceptions and throw when corresponding error codes are received from
API.
2. Option to pass a logger to the communicator to log requests and
responses
3. Setting the person's summary
4. Writing notes
5. Pedigree read
6. Deleting assertions

I've also connected the project with rdoc.info, so every time the
project updates are pushed to github, new RDocs will be generated
here:
