Added the required resource for the SobolSequenceGenerator
Modified the UniformDistribution to accept a RandomGeneratorFactory
allowing classes to provided a random generator for the distribution.
Modified the UniformDistribution to accept a RandomGeneratorFactory
allowing classes to provided a random generator for the distribution.
Updated create data to allow different UniformDistributions to be used.
PSF creator plugins to store the FWHM of the PSF
Measure FWHM using a line profile through the PSF image
Calculate PWHM across the diagonals.
Ensure the PSF models have a FWHM property
Allow PSF model random generator to be changed.

Use the PSF FWHM to compute the border for the distribution and to
compute the density threshold.
Ignore negative signal in the cumulative and % PSF signal plots.
