EnvMapper contains the environment variables as grouped by their basic type.
If a variable's type cannot be determined, it's placed in Strings.
If a variable's type is a list, it will be an []interface{} as each item may be a different variable type.
It essentially is the same as EnvMap except with the types split out for convenience.
