 +==== Methods ====
 +
 +  * Go does not have classes; a method is a function with a special receiver argument (such as "Vertex").
 +  * Value receiver versus pointer receiver (one or the other, not both)
 +  * Functions with a pointer argument must take a pointer, while methods with pointer receivers take either a value or a pointer as the receiver when they are called.
 +  * Methods with value receivers take either a value or a pointer as the receiver when they are called.
