Hostgtroup question

[Dale J. Chatham]

Apologies.  3.something...

I can include hostgroups in another hostgroup, I just cannot disinclude 
them with a "!", or so it would seem.

As a future feature request, I have two suggestions.

First, is the disinclusion of hostgroups from another hostgroup.  This 
is already done in service definitions, so the code already must exist.

The other is the ability to have empty hostgroups without complaint, 
perhaps without warning.  It allows for planning ahead and completion of 
concepts.

Thanks,

  Dale
