CYCLEFLOWCONV contains four chip generators, which generate
chips in AstroChip2.1 (running faster in AstroChip2.3), which
can be tested in the free AstroChip2.1 or AstroChip2.3.
GraphCycles detects a cycle in an undirected graph,
GraphFlow calculates the paths of a network flow through a
graph between nodes a and b, TreeDepth calculates the
depth of a tree and TreeListConv converts a Tree into
