v1.1.0 to convert to h-only style, etc.

### Releases v1.1.0

1. Convert to `h-only` style
2. Add example [multiFileProject](examples/multiFileProject) to demo for multiple-file project
3. Fix setPulseWidth() bug. Check [setPulseWidth - removed wrong map #2](#2)
4. Optimize code by using passing by `reference` instead of by `value`
