Ignore multiple fields

[pmincz]

To ignore multiple fields you have to do various FieldSerializers, i think is best to do only one passing by argument the fields with a separator like "-".

You can ignore multiple like this:

FieldSerializer[MyClass](ignore("field1") orElse ignore("field2"))

The "orElse" is a bit confusing in this context but results from partial functions being used for the ignoring, where orElse is how you combine multiple partial functions..
