scalaxb 0.2.0

• Implements support for <group>, <attributeGroup>, and <all>.
• Fixed round trip of complex types containing sequences.
• Generates toXML into the companion objects to simplify the case class.

For example,

<xs:complexType name="Address">
  <xs:sequence>
    <xs:element name="name"   type="xs:string"/>
    <xs:element name="street" type="xs:string"/>
    <xs:element name="city"   type="xs:string"/>
  </xs:sequence>
</xs:complexType>

turns to

case class Address(name: String,
  street: String,
  city: String)
