1. Add 'use strict'to example Javascript. 2. Small fixes to README.md. 3. Fix Draco compiler flag tests. 4. Fixed issue when number of quantized bits was to large. 5. Changed StartDecoding to return a value. 6. Check that num of attributes are not less than 0. 7. Check that the number of attributes is a valid value.
