Adapt code to monetization

[ctchervenkov]

Current, externalities (emissions, congestion) are calculated for each GPS trace.
To be included is the calculation of costs directly in the loop.
Some refactoring will be needed.

for the monetisation of emssisons, here is a list of the different types we can collect:
http://www.hbefa.net/e/help/HBEFA33_help_en.pdf (page 21)

regarding methane (as we just discussed in person), its a part of HC. We can collect it separately though, or just use HC for the calculations

currently, the code only collects the following:
CO("CO"), CO2_TOTAL("CO2(total)"), FC("FC"), HC("HC"), NMHC("NMHC"), NOX("NOx"), NO2("NO2"), PM("PM"), SO2("SO2");

But then, to add other emissions, ill have to re-export the hbefa database, and then edit the emissions contribute to support them. Not too much work

[ctchervenkov]

That would be great to basically include all the pollutants that are available in HBEFA.
I would also not mind to do it if you quickly show me where the database lives.

[ctchervenkov]

Yeah, for methane CH4 being part of HC, we still need to know what percentage of this total HC is CH4, no?
