//  NOTES:
//     1) be sure to make the distinguishing feature of the functional group
//        the first atom in the pattern
//     2) the RemovalReaction (if present) is used to remove the functional
//        group from the molecule. This is necessary for cases like boronic
//        ethers where the full functional group cannot be specified in SMARTS.
