Hi All,

Is there currently a class to identify if an atom is in a ring? I don't need all rings (AllRingsFinder) but a simple breath first search that will return true as soon as a ring is detected.

It means I can quickly (hopefully) tell that a bond/atom is in a ring in complex structures: http://www.ebi.ac.uk/chebi/advancedSearchFT.do?searchString=CHEBI%3A33128&submit=Search+ChEBI&queryBean.stars=3&queryBean.stars=-1
