+// Natural, Clamped, or Periodic Cubic Splines
+//
+// Input:  A list of N+1 points (x_i,a_i), 0 <= i <= N, which are sampled
+// from a function, a_i = f(x_i).  The function f is unknown.  Boundary
+// conditions are
+//   (1) Natural splines:  f"(x_0) = f"(x_N) = 0
+//   (2) Clamped splines:  f'(x_0) and f'(x_N) are user-specified.
+//   (3) Periodic splines:  f(x_0) = f(x_N) [in which case a_N = a_0 is
+//       required in the input], f'(x_0) = f'(x_N), and f"(x_0) = f"(x_N).
+//
+// Output: b_i, c_i, d_i, 0 <= i <= N-1, which are coefficients for the cubic
+// spline S_i(x) = a_i + b_i(x-x_i) + c_i(x-x_i)^2 + d_i(x-x_i)^3 for
+// x_i <= x < x_{i+1}.
+//
+// The natural and clamped algorithms were implemented from
+//
+//    Numerical Analysis, 3rd edition
+//    Richard L. Burden and J. Douglas Faires
+//    Prindle, Weber & Schmidt
+//    Boston, 1985, pp. 122-124.
+//
+// The algorithm sets up a tridiagonal linear system of equations in the
+// c_i values.  This can be solved in O(N) time.
+//
+// The periodic spline algorithm was implemented from my own derivation.  The
+// linear system of equations is not tridiagonal.  For now I use a standard
+// linear solver that does not take advantage of the sparseness of the
+// matrix.  Therefore for very large N, you may have to worry about memory
+// usage.

+/** @name MzString class
+
+  It was supposed to be used instead of std::string.
+
+  Notes for usage:
+
+  When you declare an MzString, it is initially empty. There is no need to
+  do things like #MzString a = "";#, especially not in constructors.
+
+  If you want to use a default empty MzString as a parameter, use
+
+#void foo(MzString par = MzString());   // Correct#
+
+rather than
+
+#void foo(MzString par = "");   // WRONG!#
+#void foo(MzString par = 0);    // WRONG!#
+
+(The last one is only wrong because some compilers can't handle it.)
+
+Methods that take an index as parameter all follow this rule: Valid indexes
+go from 0 to length()-1.
+\begin{tabular}{rl}
+Correct: & #foo.substr(0, length()-1);# \\
+Wrong:   & #bar.substr(0, length());#
+\end{tabular}
+
+It is important that you declare MzStrings as const if possible, because
+some methods are much more efficient in const versions.
+
+If you want to check whether a string is empty, do
+
+#if (foo.empty()) something right#
+
+rather than something along the lines of
+
+#if (!foo) completely wrong#
+
+When you use the #.copy()# method, MzString calls "#new []#", so you have to
+release the memory with #delete[]#. Don't preallocate memory.
+
+When you want to copy an MzString, just do
+
+#MzString a, b = "String";#
+#a = b; // That's it!#
+
+not something like
+
+#MzString a, b = "String";#
+#a = b.copy();#
+
+The class automatically handles deep copying when required.
