Please:

• rebase/merge from master. Another PR updated the entire gradle file
• add djomo to the readme
• run ser and deser benchmarks against jackson and paste results in here

Rebased on master and updated README.

Here are ser/deser results for djomo and Jackson from my local environment, both data models
