Ability to specify geometryName on ol.format.GeoJSON
Do not set geometry by default

A feature can have a geometry whose value is an ol.geom.Geometry instance or null.  A feature can also have no geometry property.  By default, a feature has no geometry property.  To set a geometry, one can be passed to the constructor (including null) or passed to setGeometry().

Merge pull request #2099 from tschaub/update-deps

Update dependencies.
Do not include oli.* symbols in the inheritance chain
Do not document object literals as interfaces

Instead, object literals with properties that should not be
renamed can go in externs/olx.js.
Clean up api.js
Move object literals defined in ol3 to a separate section
Move oli.* stability notes to the corresponding ol.* symbol
Remove all docstrings from oli.js

Instead, make sure that the properties are documented in the
implementing class.

Account for null or undefined geometry

The change in #2098 made it so a feature's geometry could be undefined.  This is consistent with the return type for the getGeometry method.  Where calling code needs to ensure that it has a geometry instance, it can use instanceof, goog.isDefAndNotNull(), or test for a truthy value.
