Proper documentation

[aaronchristian99]

The library is great with giving options to customize the UI with app styling and UI. But i faced an issue because of docs not being proper. There are cases where import statements are not included in the example code and I have to search through the git repo to look for what is imported. For instance, in renderCustomHeader, I followed the example and was trying to figure out wher the range() and getYear() methods are imported from. If they were described in the docs I would have not sepend time looking for those imports in the git repo.
