bmech_cocontraction

 BMECH_COCONTRACTION computes co-contraction index for muscle pairs

 ARGUMENTS
  fld       ...  str, folder to operate on

  pairs     ...  cell array of str, names of muscle pairs.
                 Example = {'L_TibAnt-L_GM','L_RF-L_Ham'} computes co-contaction 
                 for L_TibAnt and L_GM & L_RF and L_Ham muscle pairs.

 'method'  ...   str, optional. Choice of algorithm to use. 
                 Default :'Rudolph'. Other choices :'Falconer' and 'Lo2017'.

 'events'   ...  cell arrat of str. Optional, Pair of global events (only for Lo2017 method). 
                 Estimates  percent co-contraction btw the events (value stored in event). 
                 Note: Ignores events for other methods and computes co-contation line for entire data
                 Example = {'Left_FootStrike1','Left_FootStrike2'}
