[ixpmanager] Inter-POP graphs explanation

[Kostis Fardelas]

By looking at INEX's trunk.cfg,
https://github.com/inex/IXP-Manager/blob/master/application/views/_skins/inex/statistics-cli/mrtg/trunks.cfg
, I notice that there are some trunks.cfg stanzas that are not
reported to be included in application.ini (with corresponding
mrtg.trunk_graphs[] directives), namely:
core-degkcp-tcydub1-lan1-sec
core-swi1-ix1-1_swi1-ix1-2-lan1
core-swi1-ix1-1_swi1-ix2-1-lan1
core-swi1-deg1-1_swi1-deg1-3-lan1
core-swi1-tcy1-1_swi1-tcy1-4-lan1
core-swi1-deg1-1_swi1-vfw-1-lan1
core-swi1-tcy1-1_swi1-vfw-1-lan1
core-swi2-deg1-2_swi2-deg1-3-lan2
core-swi2-tcy1-2_swi2-tcy1-1-lan2
core-swi2-ix1-1_swi2-ix1-2-lan2

Are there some loose points here?
