- * @brief Holds the cluster hierarchy specification for a diagram.
- *
- * This is not considered a cluster itself, but it records all the nodes in 
- * the diagram not contained within any clusters, as well as optionally a 
- * hierarchy of clusters.
- *
- * You can add clusters via addChildCluster() and nodes via addChildNode().
- *
- * You can specify just the shapes contained in clusters, but not the nodes 
- * at this top level---the library will add any remaining nodes not appearing 
- * in the cluster hierarchy as children of the root cluster.
- *
- * It is possible to add a node as the child of two parent clusters.  In this 
- * case, the clusters will overlap to contain this (and possibly other nodes).
- * The library will warn you if you do this unless you have called the method
- * setAllowsMultipleParents() to mark this intention.
- *
- * Be careful not to create cycles in the cluster hierarchy (i.e., to mark 
- * two clusters as children of each other.  The library does not check for 
- * this and strange things may occur.

-libcola is a cross-platform C++ library for constraint graph layout. Specifically, force-directed layout using the stress-majorization method subject to separation constraints. Applications include layout with non-overlapping nodes and clusters, directed graph layout and layout preserving the crossing properties of a given starting layout.
-
-libcola is part of the 
-<a href="http://www.adaptagrams.org/">Adaptagrams project</a>. 
-There are no official releases yet, though the code is stable and 
-available from the Adaptagrams 
-<a href="https://github.com/mjwybrow/adaptagrams">github 
-repository</a>.
-
-The API is documented using Doxygen.  The documentation you are currently 
-reading can be obtained by running doxygen in the cola directory. 
-
-libcola is written and maintained by 
-<a href="http://marvl.infotech.monash.edu/~mwybrow/">Michael Wybrow</a> and
-<a href="http://marvl.infotech.monash.edu/~dwyer/">Tim Dwyer</a>,
-members of <a href="http://marvl.infotech.monash.edu/">MArVL: the Monash Adaptive Visualisation Lab</a> at Monash University, Australia.
