Fulfilling PingPong interface

Ping Server.go

package main

import (
	"context"

	pingpong "github.com/percybolmer/grpcexample/pingpong"
)

// Server is the Logic handler for the server
// It has to fullfill the GRPC schema generated Interface
// In this case its only 1 function called Ping
type Server struct {
	pingpong.UnimplementedPingPongServer

// Ping fullfills the requirement for PingPong Server interface
func (s *Server) Ping(ctx context.Context, ping *pingpong.PingRequest) (*pingpong.PongResponse, error) {
	return &pingpong.PongResponse{
