Create an template for writing tests.

This PR is intended to:

• Provide baseline coverage
• Provide a model for testing

Notes

• Run tests, including the baseline coverage test, with npm test
  • New test files should be put in tests/ and should end with .test.js
  • Coverage reports are put in coverage/lcov-report/index.html
• The baseline test simply tries to include every source file; it makes the coverage report more useful.
• Run lint with npm run lint

Changes

• Added testing + linting modules to devDependencies
• Added .jshintrc
• Moved iso-deploy to optionalDependencies, preparing for CI
• Set node 0.12 as the minimum supported engine
