Implement matching of census-like persons to vista-like trips

[dhixsingh]

We do not currently do any sensible matching of the sampled census-like persons to the generated vista-like trips. Any matching performed is arbitrary. For this reason, we do not write out the census attributes in the final MATSim XML output currently.

The code to be improved is here:

demand/R/match.R

Lines 16 to 17 in 266d481

	# TODO: to be replaced with demographics based matching
	echo(paste0('Matching census-like persons to VISTA-like plans\n'))

[dhixsingh]

The example population generation script now incorporates demographics-based trips generation. The sampled census person is matched to one of 5 VISTA demographic cohorts, and the activities/trips are generated based on the model for that cohort. Available since c45f9be.

[jafshin]

The cohort-based population generation is implemented and working since c45f9be.

However, the agent-id won't be kept at final XML which makes it complicated to joining demographics to plans. Also, there was a very low number of 65+ travellers in our cohort compared to VISTA "travellers" 65+.

Next steps:

• @alanboth - to explore if skipping those not travelling instead of removing them will address the 65+ deviation
• @dhixsingh - to add agent-id to the final XML writer

@jafshin this can be closed now?
