Davis King b655d51edf - Fixed a bug in find_max_single_variable(). It was missing a - sign on the return. 
- changed the find_*_single_variable() functions so that their interfaces are like
  the other find_* functions.
- Made the verbose printout from feature ranking more reasonable.

Davis King 0c1117df40 Renamed the two parameters in the probabilistic_decision_function from a and b 
to alpha and beta.  This is to avoid any possibility of a probabilistic_decision_function
being accidentally passed into templated code that is looking for the bias (the b element)
term of a decision_function.

Davis King e1b3a927dd Removed two try/catch blocks from the threading code. One was replaced with 
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.
