  def bootstrap(self):
    # conduct bootstrapping
    # general approach:
    # 1. randomly choose data points with replacement
    # 2. NLLS fit
    # 3. store curve and parameters
    # 4. repeat xx times
    # 5. central limit theorem says we can expect normal distribution
    #    => extract boundaries for curves at 1 sigma (68%) or 2 sigma (95%)
    # 6. plot envelope and prepare bootstrapped report
