Wrapping enumerations

This example tests SWIG's ability to wrap enumerations.

• Enum values are expressed as constants or variables in GO.
• If the enum is named, then that name, capitalized, as defined as a new type name for int. All the enum values will be defined to have that type.
• If the enum is declared at global level, then the name in Go is simply the enum value, capitalized.
• If the enum is declared within a C++ class or struct, then the name in Go is the capitalized name of the class or struct followed by the capitalized name of the enum value.

• example.h. Header file containing some enums.
• example.i. Interface file.
• runme.go. Sample Go program.
