Module from_str_allow_null

Combines from_str and allow_null.

Use this module to serialize and deserialize any T where T implements FromStr and Display to convert from or into a string. The serialized form is that of Option<String>, and a nil is deserialized to the Default value. For JSON, this means both quoted string values and null are accepted. A value is always serialized as Some<String>. Note that this can be used for all primitive data types.
