fix 2 minor bugs #88

  1. For bnlearn.py, fix bug in predict when variable has more than one state
  2. For learn_discrete_bayes_net.py, due to the limited precision of floating-point calculations in computers, a zero value may occur at line 172. This can lead to a ValueError: math domain error when calculating math.log at line 322 in subsequent computations. After researching for a solution, I have added a very small value (1e-10) at this point to perform smoothing. Now the program runs without any issues. If there are any issues with this approach, please let me know, and I will try to make modifications.
