combinator generates a slice of all possible value combinations for any given
struct and a set of its potential member values. This can be used to generate
extensive test matrixes among other things.

Name string
Age uint

}
/*
Define potential test values. Make sure the struct's fields share the name and
type of the structs you want to generate.
