DOWNSAMPLEDATA - Downsamples DynaSim data structre data

 Usage:
   data_out = dsCalcFR(data,'option',value)

 Inputs:
   - data: DynaSim data structure (see dsCheckData)
   - ds: number of datapoints to downsample

 Outputs:
   - data_out: data structure all fields replaced by their decimated values
