Added code to read a list of steroid levels from stdin, rather than from
a list in a Matlab binary file. My intention is that the list of steroid
levels can then be pulled out of a database/whatever and fed into the stdin
of the prediction program. This makes the prediction software more
flexible.
Created an Octave script to print out the steroid levels from a Matlab
binary file, in a form that can be read from stdin by the new reading code.
