I want belongs_to method back!

Before the release of 0.2, I found that there's a hard-to-resolve bug in BaseModel.belongs_to method. So I temporarily remove it from the 0.2 release. However, I tried a hack that make BaseModel.belongs_to more reasonable. In 0.2.1 release, this class_method will be officially provided.

Now you can download the nightly release from the project home to have BaseModel.belongs_to method.
