-Package mergo merges same-type structs and maps by setting default values in zero-value fields.
-
-Mergo won't merge unexported (private) fields but will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection).
-
-Usage
-
-From my own work-in-progress project:
-
-	type networkConfig struct {
-		Protocol string
-		Address string
-		ServerType string `json: "server_type"`
-		Port uint16
-	}
-
-	type FssnConfig struct {
-		Network networkConfig
-	}
-
-	var fssnDefault = FssnConfig {
-		networkConfig {
-			"tcp",
-			"127.0.0.1",
-			"http",
-			31560,
-		},
-	}
-
-	// Inside a function [...]
-
-	if err := mergo.Merge(&config, fssnDefault); err != nil {
-		log.Fatal(err)
-	}
-
-	// More code [...]
