Arguments

x	value of any data-GeoJSON object. required.
type	expected GeoJSON type. required.
name	name of calling function. required.
lint	(logical) Lint or not. Uses geojsonhint. Takes up increasing time as the object to get linted increases in size, so probably use by default for small objects, but not for large if you know they are good geojson objects. Default: FALSE
