Assigning nlobjRequest parameters to nlobjRecord (world's smalled class!)

If you are like me and use associative array/enum for your field names (you should, it's the gift that keeps giving!) then you might find this little nugget useful.  It's also the world's smallest class (unconfirmed).

 //  usage  var assessment = nlapiLoadRecord(REC_IDS.PATIENT_ASSESSMENT, id);  Guard.NotNull(assessment, 'Failed loading Patient Assessment record ' + id);    var setter = new SetRecordFieldsFromParameters(assessment, request);  setter.Set(PAT_ASSESS_FLD.START_TM);  setter.Set(PAT_ASSESS_FLD.TRNG_LOC);  setter.Set(PAT_ASSESS_FLD.LOC_OTHR);  // [...]    //  setter class (so cute!)  function SetRecordFieldsFromParameters(record, request)  {      this._record  = record;      this._request = request;  }    SetRecordFieldsFromParameters.prototype =   {      Set: function(fieldId)      {          this._record.setFieldValue(fieldId, this._request.getParameter(fieldId));      }  }        //  field names  var PAT_ASSESS_FLD =  {      START_TM     : 'custrecord_pat_assess_start_time',      TYPE         : 'custrecord_pat_assess_type',      PATIENT      : 'custrecord_pat_assess_patient',      ASSESS_BY    : 'custrecord_pat_assess_assessed_by',      Order        : 'custrecord_pat_assess_order',      TRNG_LOC     : 'custrecord_pat_assess_training_location',      LOC_OTHR     : 'custrecord_pat_assess_train_loc_other',      TRNG_BY      : 'custrecord_pat_assess_train_conducted_by',      TRNG_BY_OTHR : 'custrecord_pat_assess_train_conducted_ot',      GROK_TRN     : 'custrecord_pat_assess_understood_traing',      COND_TREATED : 'custrecord_pat_assess_cond_undr_treatmnt',      PROD_WRKNG   : 'custrecord_pat_assess_treatmnt_effective',      TRT_FREQ     : 'custrecord_pat_assess_treatmnt_frequency',
