Returns true iff the geometries of two features are within a specified distance.
Feature.withinDistance(right, distance, maxError, proj)
|Element||The feature containing the geometry used as the left operand of the operation.|
|Element||The feature containing the geometry used as the right operand of the operation.|
|Float||The distance threshold. If a projection is specified, the distance is in units of that projected coordinate system, otherwise it is in meters.|
|ErrorMargin, default: null||The maximum amount of error tolerated when performing any necessary reprojection.|
|Projection, default: null||The projection in which to perform the operation. If not specified, the operation will be performed in a spherical coordinate system, and linear distances will be in meters on the sphere.|
