This function returns a reference to a SMILES parser
object. If you are parsing multiple SMILES strings using multiple
calls to parse.smiles, it is
preferable to create your own parser and supply it to
parse.smiles rather than forcing that function
to instantiate a new parser for each call
Value
A `jobjRef` object corresponding to the CDK SmilesParser class
