+
+ This is an AES implementation that uses only 8-bit byte operations on the
+ cipher state (there are options to use 32-bit types if available).
+
+ The combination of mix columns and byte substitution used here is based on
+ that developed by Karl Malbrain. His contribution is acknowledged.

+
+/* This version derived by Mark Tillotson 2012-01-23, tidied up, slimmed down
+   and tailored to 8-bit microcontroller abilities and Arduino datatypes.
+
+   The s-box and inverse s-box were retained as tables (0.5kB PROGMEM) but all 
+   the other transformations are coded to save table space.  Many efficiency 
+   improvments to the routines mix_sub_columns() and inv_mix_sub_columns()
+   (mainly common sub-expression elimination).
+
+   Only the routines with precalculated subkey schedule are retained (together
+   with set_key() - this does however mean each AES object takes 240 bytes of 
+   RAM, alas)
+
+   The CBC routines side-effect the iv argument (so that successive calls work
+   together correctly).
+
+   All the encryption and decryption routines work with plain == cipher for
+   in-place encryption, note.
