I'm thinking the XML format of the data as a flat list of points (X1, Y1, Z1, X2, Y2, Z2, ...) would make the import export code simpler, and it isn't more or less readable in an XML format (for my brain anyway).

@gonuke Thanks for this PR! Out of curiosity, what is the intended application of this feature?

We have a user who has an existing approximation of a volumetric source by a high density list of isotropic point sources. They want to use that source for comparison to other simulations. |

While it may have been elegant to add an Thus, I've relied on just reading a list of doubles and packing them into |

I just pushed a couple of small changes, but this looks good to me! @paulromano, you mentioned you'd like to have a look at this as well, so I'll give you a little time to review.

Pinging @paulromano to see if this can move forward? |

Thanks @gonuke! I did a bit of refactoring and simplification. I'm good to merge but before I do, let me know if you object to any of my changes.

All looks good to me - thanks @paulromano |

Description
Allows users to define a list of points in space, each with a different relative intensity, to be sampled discretely. This is a valid
SpatialDistributionand can be used anywhere that aSpatialDistributionis valid.Fixes #3159
