<div class="block">A singleton class that provides algorithms for graphs. Assume these
variables for the following examples:<br>
<code>
mxICostFunction cf = mxDistanceCostFunction();
Object[] v = graph.getChildVertices(graph.getDefaultParent());
Object[] e = graph.getChildEdges(graph.getDefaultParent());
mxGraphAnalysis mga = mxGraphAnalysis.getInstance();
</code>
<h3>Shortest Path (Dijkstra)</h3>
For example, to find the shortest path between the first and the second
selected cell in a graph use the following code: <br>
<br>
<code>Object[] path = mga.getShortestPath(graph, from, to, cf, v.length, true);</code>
<h3>Minimum Spanning Tree</h3>
This algorithm finds the set of edges with the minimal length that connect
all vertices. This algorithm can be used as follows:
<h5>Prim</h5>
<code>mga.getMinimumSpanningTree(graph, v, cf, true))</code>
<h5>Kruskal</h5>
<code>mga.getMinimumSpanningTree(graph, v, e, cf))</code>
<h3>Connection Components</h3>
The union find may be used as follows to determine whether two cells are
connected: <code>boolean connected = uf.differ(vertex1, vertex2)</code>.</div>

<div class="block">Returns the minimum spanning tree (MST) for the graph defined by G=(E,V).
The MST is defined as the set of all vertices with minimal lenths that
forms no cycles in G.<br>
This implementation is based on the algorihm by Kruskal. It uses
O(|E|log|E|)=O(|E|log|V|) time for sorting the edges, O(|V|) create sets,
O(|E|) find and O(|V|) union calls on the union find structure, thus
yielding no more than O(|E|log|V|) steps. For a faster implementatin</div>
