getAllRxnsFromGenes

 getAllRxnsFromGenes
   Given a list of reactions, this function finds the associated genes in
   the template model and gives all reactions that are annotated by these
   genes.

   model       a model structure
   rxns        either a cell array of IDs, a logical vector with the
               same number of elements as reactions in the model, or a
               vector of indexes

   allRxns     either a cell array of IDs, a logical vector with the
               same number of elements as reactions in the model, or a
               vector of indexes, dependent on the format of rxns

 Usage: allRxns=getAllRxnsFromGenes(model,rxns)
