Internal method to wrap cycle computations which <i>should</i> be
tractable. That is they currently won't throw the exception - if the
method does throw an exception an internal error is triggered as a sanity
check.

@param finder    the cycle finding method
@param container the molecule to find the cycles of
@return the cycles of the molecule
