  FT_HEADMODEL_LOCALSPHERES constructs a MEG volume conduction model in
  with a local sphere fitted to the head or brain surface for each separate

  Use as
    headmodel = ft_headmodel_localspheres(mesh, grad, ...)
  Optional arguments should be specified in key-value pairs and can include
    radius    = number, radius of sphere within which headshape points will
                be included for the fitting algorithm
    maxradius = number, if for a given sensor the fitted radius exceeds
                this value, the radius and origin will be replaced with the
                single sphere fit
    baseline  = number
    feedback  = boolean, true or false
