Spatial filters

[michaeldgraham]

This PR contains initial support for Point type spatial filtering. Given a Point type field named, for example, location, the filtering fields location, location_not, location_distance, location_distance_lt, location_distance_lte, location_distance_gt, location_distance_gte will now be generated.

To support the distance filters, the schema augmentation process now generates the following input object type definition,

input _Neo4jPointDistanceFilter {
  point: _Neo4jPointInput!
  distance: Float!
}

Tests

The following tests have been added to filterTck.md:

Spatial field equal to given value
Spatial field different from given value
Spatial field distance with given Point value equal to given value
Spatial field distance with given Point value less than given value
Spatial field distance with given Point value less than or equal to given value
Spatial field distance with given Point value greater than given value
Spatial field distance with given Point value greater than or equal to given value
Spatial field exists
Spatial field does NOT exist
Spatial fields on relationship exist
Spatial field does NOT exist on related node
Spatial field on related node equal to given value
Spatial field on related node equal to given year OR does NOT exist
Spatial and scalar field on relationship match given logical AND filters

The following tests have been added to integration.test.js:

Spatial - filtering - field equal to given value
Spatial - filtering - field different from given value
Spatial - filtering - field distance with given Point value less than given value
