Made changes:

- Updated .gitignore to include specs
- Re-licensed to MPL-2.0 as I want any modifications to be pushed back
  to the main codebase so that the ecosystem can benefit from developer
  adoption
- Updated LICENSE & shard.yml with new license
- Changed author to personal email as this is not being done for my
  company
