Average velocity of the distribution of atoms inside the oven here cancels with the normalization of the distribution of atoms coming out of the oven so it can be removed as long as that normalization is also removed!

Removed the multiplication of the full Clausing Factor since the correct flux coming out of the oven is obtained by accounting for the clipping by the aperture which is done by numerically integrating the angular distribution till the exit divergence angle that is limited by the aperture to obtain what is called the "reduced" Clausing Factor. This is calculated in the initialVelocitySampling and multiplied to this flux to get the "reduced" flux.

Major change how the loading rate is calculated from the raw output of the simulator - Zero crossing of the autocorrelation of the time series - which is the number of loaded atoms at each time step - is used to determine the length of each of a 1000 bootstrap samples obtained by sampling with replacement. Mean in each sample is calculated and a sampling distribution of means obtained. The capture ratio is the mean of this distribution which when multiplied by the "reduced" flux gives the loading rate. Standard Error and 95% confidence interval are also calculated from the sampling distribution.
