It deals with data using reflection.
If you pass data as struct, then "$" is that struct, and $.Name, and
,Name refers to the field named Name in that struct
If you pass data as a map[string]interface{}, then .Name refers to the
value data["Name"]
If all you need is to pass ENV, you can make it a function using
Template.Funcs(), and call ENV to get env values. However, I think
passing in a map is the easiest solution.
