+- Update to version 4.100 (Dirt Cruiser)
+  + added normalise() for normalising vectors to unit p-norm
+  + extended the field class to handle 3D layout
+  + extended eigs_sym() and eigs_gen() to obtain eigenvalues of
+    various forms (eg. largest or smallest magnitude)
+  + automatic SIMD vectorisation of elementary expressions
+    (eg. matrix addition) when using Clang 3.4+ with -O3
+    optimisation
+  + faster handling of sparse submatrix views
+  + workaround for a bug in LAPACK 3.4
+- Changes from version 4.000.4:
