An interface table that provides core host API functions for registering components and interfaces.
The version of the API that the host is using
During initialisation of your component (via Initialise or InitialiseGUI) the host framework passes you a pointer to a HostAPI for you to use to access host functions. You should bind to the host by calling WG_BIND_HOST with the passed in HostAPI pointer as a parameter.
See WG_BIND_HOST for an example of binding to the host API
