TOML parser parses a TOML file to a map[string]interface{} and then traverses the map and adds values into the config store flattening the TOML using dot notation for keys.
Ex:
foo = bar
[nested]
firstName = "john"
lastName = "doe"
list = [1, 2]
Will add the following key/value to the config
"foo" => "bar"
"nested.firstName" => "john"
"nested.lastName" => "doe"
"nested.list" => []int{1,2}
err := kptoml.Parser.Parse(strings.NewReader(`foo: "bar"`), konfig.Values{})
