	// This diff-sequences package implements the linear space variation in
	// An O(ND) Difference Algorithm and Its Variations by Eugene W. Myers

	// Relationship in notation between Myers paper and this package:
	// A is a
	// N is aLength, aEnd - aStart, and so on
	// x is aIndex, aFirst, aLast, and so on
	// B is b
	// M is bLength, bEnd - bStart, and so on
	// y is bIndex, bFirst, bLast, and so on
	// Δ = N - M is negative of baDeltaLength = bLength - aLength
	// D is d
	// k is kF
	// k + Δ is kF = kR - baDeltaLength
	// V is aIndexesF or aIndexesR (see comment below about Indexes type)
	// index intervals [1, N] and [1, M] are [0, aLength) and [0, bLength)
	// starting point in forward direction (0, 0) is (-1, -1)
	// starting point in reverse direction (N + 1, M + 1) is (aLength, bLength)

	// The “edit graph” for sequences a and b corresponds to items:
	// in a on the horizontal axis
	// in b on the vertical axis
	//
	// Given a-coordinate of a point in a diagonal, you can compute b-coordinate.
	//
	// Forward diagonals kF:
	// zero diagonal intersects top left corner
	// positive diagonals intersect top edge
	// negative diagonals insersect left edge
	//
	// Reverse diagonals kR:
	// zero diagonal intersects bottom right corner
	// positive diagonals intersect right edge
	// negative diagonals intersect bottom edge

	// The graph contains a directed acyclic graph of edges:
	// horizontal: delete an item from a
	// vertical: insert an item from b
	// diagonal: common item in a and b
	//
	// The algorithm solves dual problems in the graph analogy:
	// Find longest common subsequence: path with maximum number of diagonal edges
	// Find shortest edit script: path with minimum number of non-diagonal edges

	// Input callback function compares items at indexes in the sequences.

	// Output callback function receives the number of adjacent items
	// and starting indexes of each common subsequence.
	// Either original functions or wrapped to swap indexes if graph is transposed.
	// Indexes in sequence a of last point of forward or reverse paths in graph.
	// Myers algorithm indexes by diagonal k which for negative is bad deopt in V8.
	// This package indexes by iF and iR which are greater than or equal to zero.
	// and also updates the index arrays in place to cut memory in half.
	// kF = 2 * iF - d
	// kR = d - 2 * iR
