A MIMEHeader represents a MIME-style header mapping keys to sets of values.
type MIMEHeader map[string][]string
Add adds the key, value pair to the header. It appends to any existing values associated with key.
func ( MIMEHeader) (,  string) {
	 = CanonicalMIMEHeaderKey()
	[] = append([], )
}
Set sets the header entries associated with key to the single element value. It replaces any existing values associated with key.
func ( MIMEHeader) (,  string) {
	[CanonicalMIMEHeaderKey()] = []string{}
}
Get gets the first value associated with the given key. It is case insensitive; CanonicalMIMEHeaderKey is used to canonicalize the provided key. If there are no values associated with the key, Get returns "". To use non-canonical keys, access the map directly.
func ( MIMEHeader) ( string) string {
	if  == nil {
		return ""
	}
	 := [CanonicalMIMEHeaderKey()]
	if len() == 0 {
		return ""
	}
	return [0]
}
Values returns all values associated with the given key. It is case insensitive; CanonicalMIMEHeaderKey is used to canonicalize the provided key. To use non-canonical keys, access the map directly. The returned slice is not a copy.
func ( MIMEHeader) ( string) []string {
	if  == nil {
		return nil
	}
	return [CanonicalMIMEHeaderKey()]
}
Del deletes the values associated with key.
func ( MIMEHeader) ( string) {
	delete(, CanonicalMIMEHeaderKey())
