Create a simple/quick wrapper call

[mooeypoo]

Right now, the library requires initialization and allows to customize where the output is shown. While that's intended to give freedom to the user, it makes it too difficult for direct and plain usage.

There can be a wrapper that calls for basic initialization and reads content in the body, which means that users will be able to attach the library and css files and immediately get the functionality of popups that are also mobile friendly. The implementation already exists in the WordPress plugin, and can be done on a plain HTML.
