 /** Extract preferences by prefix.
- * 
+ *
  * This function returns a lambda which, given
  * a key or a prefix, extracts the relevant
  * preferences from the designated preferences
  * store.
- * 
+ *
  * For instance, assume preferences = {
  *   "a.b.c.d": 1,
  *   "a.b.e.f": 2,
  *   "g.h": 3
  * }
- * 
+ *
  * And λ = preferencesλ(preferences). Then:
- * 
+ *
  * λ("a.b") → { "a.b.c.d": 1, "a.b.e.f": 2 }
  * λ("a.b.e.f") → { "a.b.e.f": 2 }
  * λ("g.x", {"g.x.": 99}) → { "g.x.": 99 }
  * λ("a.c", {"g.x.": 99}) → { "g.x.": 99 }
- * 
+ *
  * Note from the last  two examples that a default value
  * may be provided and will be returned if a key does
  * not exist or is not searched for.
