+/* Some interesting things implemented
+
+   - There is a macro that writes out "cbbrowne" just because I could
+   - There is a (somewhat cruddy) linear congruential random number
+     generator.
+     - I would like to be seeding it with clock info to make it look
+       more random
+   - There are two macros that use the random number generators
+     - one, M_RANDDIGIT, generates a random digit based on state
+       of the random number generator
+     - the other, M_RANDLETTER, generates a random letter based on state
+       of the random number generator
+     - in both
