Detailed Description

A Linkage is a ReferentialSkeleton with the special property that all the BodyNodes included in it form a contiguous graph.

This property is only guaranteed during construction of the Linkage. After the Linkage has been constructed, a user might alter how the BodyNodes in a Linkage are assembled. The function Linkage::isAssembled() can be used to check whether the Linkage is still assembled. The function Linkage::satisfyCriteria() can be used to redefine the Linkage so that the original Linkage::Criteria is met again. The function Linkage::reassemble() will reassemble the BodyNodes so that they match whatever assembly they had the last time Linkage::reassemble() was called (or the assembly that they had when the Linkage was constructed, if Linkage::reassemble has never been called).
