Added a script and log for calculating the exponential curve parameter errors via bootstrapping.
This uses the data at http://thread.gmane.org/gmane.science.nmr.relax.devel/6807/focus=6840 and
calculates the parameter errors via bootstrapping. As the parameters at the minimum are the exact
parameter values, bootstrapping and Monte Carlo simulation converge and hence this is a true error
estimate. 200,000 simulations where used, so the parameter errors are extremely accurate.
