-		 * Algorithm:
-		 *
-		 * Conflicts occur when two fields exist in a query which will produce the same
-		 * response name, but represent differing values, thus creating a conflict.
-		 * The algorithm below finds all conflicts via making a series of comparisons
-		 * between fields. In order to compare as few fields as possible, this makes
-		 * a series of comparisons "within" sets of fields and "between" sets of fields.
-		 *
-		 * Given any selection set, a collection produces both a set of fields by
-		 * also including all inline fragments, as well as a list of fragments
-		 * referenced by fragment spreads.
-		 *
-		 * A) Each selection set represented in the document first compares "within" its
-		 * collected set of fields, finding any conflicts between every pair of
-		 * overlapping fields.
-		 * Note: This is the *only time* that a the fields "within" a set are compared
-		 * to each other. After this only fields "between" sets are compared.
-		 *
-		 * B) Also, if any fragment is referenced in a selection set, then a
-		 * comparison is made "between" the original set of fields and the
-		 * referenced fragment.
-		 *
-		 * C) Also, if multiple fragments are referenced, then comparisons
-		 * are made "between" each referenced fragment.
-		 *
-		 * D) When comparing "between" a set of fields and a referenced fragment, first
-		 * a comparison is made between each field in the original set of fields and
-		 * each field in the the referenced set of fields.
-		 *
-		 * E) Also, if any fragment is referenced in the referenced selection set,
-		 * then a comparison is made "between" the original set of fields and the
-		 * referenced fragment (recursively referring to step D).
-		 *
-		 * F) When comparing "between" two fragments, first a comparison is made between
-		 * each field in the first referenced set of fields and each field in the the
-		 * second referenced set of fields.
-		 *
-		 * G) Also, any fragments referenced by the first must be compared to the
-		 * second, and any fragments referenced by the second must be compared to the
-		 * first (recursively referring to step F).
-		 *
-		 * H) When comparing two fields, if both have selection sets, then a comparison
-		 * is made "between" both selection sets, first comparing the set of fields in
-		 * the first selection set with the set of fields in the second.
-		 *
-		 * I) Also, if any fragment is referenced in either selection set, then a
-		 * comparison is made "between" the other set of fields and the
-		 * referenced fragment.
-		 *
-		 * J) Also, if two fragments are referenced in both selection sets, then a
-		 * comparison is made "between" the two fragments.
