Make this library 'developer-friendly'

[AshBardhan]

Hi Andy,

I've done the following changes in order to make this library:

1. Code indentation of multiple files.
2. Rearranged directory structure
   • src - the source raw files (where any one can change as required).
   • dist - all the final build files and their minified versions.
   • demo - some sample index.html and index2.html files for testing.
3. Added grunt node packages and related tasks which will compile files in src folder into dist folder.
4. Added CONTRIBUTING.md file where development related steps are mentioned.
5. Updated bower.json by adding some ignored files, which won't be downloaded if user install this library from bower.
6. Added .gitignore file.

Hope to get quick response.

Thanks.
