 __Notes__
-- the swig interface files (*.i) and cgo directives __must__ match the equivalent files in the respective infospace and vank libraries.
-
 - the cgo directives are generated by Makefilie.cgo from vank, and Makefile.icgo from infospace. the swig compile command adds the directives to the top of vank_go.go as __import "C"__.
 
-- when the pimary interface file vank.i is modified, swig compilation may assign go type names a different unique numeric sub-string referring to the wrapped c++ types that cause a subsequent go build to fail. When this happens, interface files that define go types for c++ types need to be modified and re-compiled with swig. the following patterns highlight the substring that should match:
