Callbacks
Application modules implementing the IBC module must implement the following callbacks as found in 05-port. More information on how to implement these callbacks can be found in the implementation guide.
// IBCModule defines an interface that implements all the callbacks
// that modules must define as specified in ICS-26
type IBCModule interface {
