accessors for gridpoints and corresponding densities

[tpapp]

It is unclear if eg for univariate densities the slots x and density can be used (ie are part of the API and can be expected to be stable, not an internal implementation detail).

It would be great to document this, or alternatively provide accessor functions. Similarly for bivariate.

If the package maintainers clarify their intention, I would be happy to make a PR.

Could also help with #66.

Bump --- can anyone clarify this?

[tpapp]

@simonbyrne , can you help me with this? Again, I just need a decision on what would be preferred, happy to make the PR.

This package would benefit greatly from these accessors and a tutorial. I would prefer to have documented functions for access to prevent breakage if internals get moved around.

I'm afraid I don't have the bandwidth to contribute to this repository for the forseeable future. @tpapp and @tlnagy I've added you as collaborators, please do as you see fit.

[tpapp]

@simonbyrne, are you sure you added me as a collaborator? I don't seem to have access rights. In any case, I will just fork in the meantime.
