argument may be quoted and escaped as necessary to ensure that POSIX shells
treat the returned value as a literal representing the argument passed to
this function. Parameter (variable) expansions beginning with $ are allowed
to remain intact without escaping the $, to allow the argument to contain
references to variables to be expanded by the shell.

Args:
graph: A list of node names.
get_edges: A function mapping from node name to a hashable collection
of node names which this node has outgoing edges to.
Returns:
A list containing all of the node in graph in topological order.
It is assumed that calling get_edges once for each node and caching is
cheaper than repeatedly calling get_edges.
Raises:
CycleError in the event of a cycle.
Example:
graph = {'a': '$(b) $(c)', 'b': 'hi', 'c': '$(b)'}
def GetEdges(node):
return re.findall(r'\$\(([^))]\)', graph[node])
print TopologicallySorted(graph.keys(), GetEdges)
