being accidentally passed into templated code that is looking for the bias (the b element)
term of a decision_function.

the RAII equivalent and the other was the final catch block to log uncaught exceptions
from the user and then abort the program.  The code now lets the exception escape
to the operating system so that it is easier to debug uncaught exceptions.

Most of these changes are just rearrangements of the old code.  However, I also changed
the starting value of a line search and also removed some unneeded calls to the objective
function and its derivative in the course of doing the refactoring.  This has all resulted
in a significant reduction in calls to the objective function.

were easier on the eyes but not using the SURF window size is probably
confusing.
