The "standard" pattern for bean usage is to use the default constructor
and set any properties with mutator (setter) methods. To use the
BeanSerializer with your MyDouble class, MyDouble must have a "double"
property that is read/write, i.e. it either has public getter/setter
methods or the field is public.
