The superclass for all builders. A builder is a class that provides the structure and content of API documentation. A builder is completely doclet independent which means that any doclet can use builders to construct documentation, as long as it implements the appropriate writer interfaces. For example, if a doclet wanted to use ConstantsSummaryBuilder to build a constant summary, all it has to do is implement the ConstantsSummaryWriter interface and pass it to the builder using a WriterFactory. 
This is NOT part of any supported API.
 If you write code that depends on this, you do so at your own risk.
 This code and its internal interfaces are subject to change or
 deletion without notice.
