This action launches the device's native SMS (text message) compose sheet. No iOS or Android
class files need to be added to the project. If the JSON data passed to the method
includes number and / or a message the SMS compose sheet is pre-filled with
the values. Pre-filling the number and / or message allows users to easily send you a text.

Not all iOS devices can send SMS messages, including most simulators.

Most folks use the control panel to configure the JSON data for this plugin but it's useful to
see what it may look like. This is the simplest example.

     "textMessage":"question about your app...",
     "textToNumber":"123456789"
