Documentation for a group of variables

With Doxygen, it is possible to create a grouping of variables (and subroutines, types, etc) and give documentation for all of them as a whole. Example of what I mean:

```
!> \name Huygens surface existence
!! These variables specify if correction terms should be applied in this block
!! at a given side for a given field.
!>\{
logical :: xlo_e = .false., xlo_h = .false., xhi_e = .false., xhi_h = .false.
logical :: ylo_e = .false., ylo_h = .false., yhi_e = .false., yhi_h = .false.
logical :: zlo_e = .false., zlo_h = .false., zhi_e = .false., zhi_h = .false.
!>\}
```
Doxygen creates a section for it:

I cannot find a comparable feature in FORD. When the number of variables is large and the same documentation applies to all, duplication is not attractive.
