@brief The LofeltHaptics class
@discussion Defines the API of Lofelt SDK for iOS.
The LofeltHaptics class is not thread safe and can only be used from
the main thread.
When the app is put into the background, Core Haptics will not allow
playing any haptics. LofeltHaptics will detect this situation and cease
all activity.
When the app is put into the foreground again, Core Haptics will allow
playing haptics again, and LofeltHaptics re-initalizes itself. However,
haptics that were interrupted when the app was backgrounded do not
automatically resume and need to be started again by calling @c play().
