callbacks.go

/*
The following functions provide Go language callbacks that libcircle
can invoke.  They wrap libcircle datatypes with Go interfaces for a
more Go-like feel.  Because the functions are declared with "//export"
they are incompatible with cgo files that declare C code, such as
circle.go.  Therefore, callUserCBCreate and callUserCBProcess must
appear in a separate file.
