\brief Provides settings for virtual keyboard.
This module provides VirtualKeyboarSettings instance,
which can be used for configuring virtual keyboard settings.
Note that settings have only effect during current application
lifetime, i.e. the configuration changes are not persistent.
For example, to change the keyboard style in application:
\code
Component.onCompleted: VirtualKeyboardSettings.styleName = "retro"
\endcode
