A space predicate takes a space as an argument and returns a boolean indicating whether or not that space passed some test.

Subclasses:

• Adjacency_Predicate

Implementations:

• Space_Predicate_Bin
  Creates a predicate that tests if feature values along a particular coordinate dimension of two objects fall into the same bin.
  Constructor args: double bin_width, Field, int coord_num=0.
• Space_Predicate_Feature_Distance
  Creates a predicate that tests if the distance between features of two objects is within a threshold.
  Constructor args: Field, double threshold=0.
