Hash for geocoder not working

[hanbyul-here]

Hash for geocoder looks up the place key of which value should be gid. and callsplace function of geocoder.

This function used to place a marker on the map, but no more (https://github.com/mapzen/leaflet-geocoder/blob/6b20d53f39fdcad99acb4092d8270137f19ea7c4/src/core.js#L303). (It still makes a call, but doesn't do anything with the result)

so Leaflet geocoder officially doesn't support place call results. However the result can be still accessed through results event : https://github.com/mapzen/leaflet-geocoder#interaction-behavior

• Working on this branch
• it becomes funky when used with Leafet Routing Machine, because both of them fight to have priority setting the view. At least mapzen.js should throw warning message that geocoder and routing machine wouldn't work that nicely together
• Set up the test dedicated to geocoder hash
• Change lat, lng, zoom hash value according to selected place
