Re-enable doxygen processing of the "Remote" directories.

### Description

Disabled in #116 until sphinx based examples and potential self-referential links can be evaluated and fixed.

### Expected information

A discussion is needed about what to require/expect/allow for doxygen generation from the remote modules.

### Actual information
The desired behavior of doxygen wrapping of the remote modules is not clear. If "generate documentation" is requested, which modules should be required?
