add hasAuthorsAtR field in dbMat

[LiNk-NY]

Hi Lori, @lshep

It would be good to include the hasAuthorsAtR field in the VIEWS file.
This would help us identify more easily what packages need to use this field in the DESCRIPTION file.

https://bioconductor.org/packages/release/bioc/VIEWS
https://bioconductor.org/packages/devel/bioc/VIEWS

related to: seandavi/BiocPkgTools#65

[lshep]

we'll need to test this to make sure it works properly since if the VIEWS files does not get generated it will block updates and landing page generation on the website for packages.

@jwokaty with the reorg of code is this run by the central builder on jetstream?

[hpages]

It is run on the central builder in the biocpush account but biocViews will need to be updated manually there.

@LiNk-NY It should be:

identical(length(field), 1L) && !is.na(field) 

rather than:

!is.na(field) && identical(length(field), 1L)

If length(field) happens to be != 1 then !is.na(field) will be a logical vector of length !=1 which will cause problems in the context of &&. By putting it after the && it will only be evaluated if length(field) is 1.

Also no need to use identical() here, length(field) == 1L is just fine and more natural.
