The superclass for all member builders.  Member builders are only executed
within Class Builders.  They essentially build sub-components.  For example,
method documentation is a sub-component of class documentation.
 
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.
