Update default min_zoom, max_zoom values for neighbourhoods

[nvkelso]

From the WOF documentation we've refined this a bit from the default 15 min_zoom and 16 max_zoom to defaults per the 4 related "neighbourhood" placetypes.

• tilequeue/tilequeue/wof.py

  Lines 34 to 45 in b0a6bc9

  	neighbourhood_placetypes_to_int = dict(
  	neighbourhood=1,
  	microhood=2,
  	macrohood=3,
  	borough=4,
  	)
  	neighbourhood_int_to_placetypes = {
  	1: 'neighbourhood',
  	2: 'microhood',
  	3: 'macrohood',
  	4: 'borough',
  	}

• tilequeue/tilequeue/wof.py

  Lines 290 to 308 in b0a6bc9

  	default_min_zoom = 15
  	default_max_zoom = 16
  	min_zoom = props.get('mz:min_zoom')
  	if min_zoom is None:
  	min_zoom = default_min_zoom
  	else:
  	try:
  	min_zoom = float(min_zoom)
  	except ValueError:
  	return failure('mz:min_zoom not float: %s' % min_zoom)
  	max_zoom = props.get('mz:max_zoom')
  	if max_zoom is None:
  	max_zoom = default_max_zoom
  	else:
  	try:
  	max_zoom = float(max_zoom)
  	except ValueError:
  	return failure('mz:max_zoom not float: %s' % max_zoom)

For existing features, probably don't modify the existing min_zoom and max_zoom values. But for new features, do the following:

• borough:
  • Default: min_zoom: 10
  • Default: max_zoom: 13
• neighbourhood:
  • Default: min_zoom: 15
  • Default: max_zoom: 18
• macrohood:
  • Default: min_zoom: 13
  • Default: max_zoom: 15
• microhood:
  • Default: min_zoom: 16
  • Default: max_zoom: 18
