Adapted Bayesian Knowledge Tracing (Brute Force) BKT-BF

I adapted the original Bayesian Knowledge Tracing (Brute Force) BKT-BF code (www.columbia.edu/~rsb2162/BKT-BruteForce.zip) to allow data in chronological order but not necessary sorted on Skill and Student (can be mixed). Moreover, the dataset can have free number of columns in any order and any separator (coma, tab, etc.)

I didn't tested it thoroughly but at least it works for my needs.

Parameters (1 is the first one): 

  skillPos = Skill column position 

  studentPos = Student column position

  rightPos = Right column position

  separator = Separator (comma(,) , tab(tab), etc.)

$> java ComputeKTparamsAll ./data.txt 4 3 6 tab

In  this example, it gets the model from the data.txt dataset where the skill column is the 4th, student column is the 3rd, right column is the 6th and the columns are separated by tab.
