Add @PreSerialize annotation

[GoogleCodeExporter]

1.remove unused field value
public class User{
private String username;
private String password;
@PreSerialize
public void preSerialize(){
this.password = null;
}
}

2.set getter's value to field
because gson doesn't support serialize getter method

public class TreeNode{
private Collection<TreeNode> children;
private boolean hasChildren;
@PreSerialize
public void preSerialize(){
this.hasChildren = isHasChildren();
}
public boolean isHasChildren(){
return this.children != null && this.children.size() != 0;
}
}

Sorry, but I do not fully understand the requirements for this new PreSerialize
annotation.

This could done similar to the PostCreate (Issue #144) or it could be done with 
a
TypeConverter where you can do some special behaviour and than use the
SerializationContext and serialize this (Issue #43).

I can't find @PostCreate,I think it's for deserialization not serialization
TypeConverter need exact class
registerTypeAdapter(Foo.class, new FooTypeAdapter()) doesn't works for subclass 
of Foo
it must be 
registerTypeAdapter(ChildOfFoo.class, new 
FooTypeAdapter()).registerTypeAdapter(Child2OfFoo.class, new 
FooTypeAdapter()).registerTypeAdapter(Child3OfFoo.class, new 
FooTypeAdapter())....
