modified method of getting bigram totals for conditional probability
for bigrams "xy", we require the total number of bigrams beginning with "x" in order to calculate the probability that y should be the next character in the sequence.  the method of doing this was to iterate through the bigrams matrix & sum the frequencies in a row.  created an array to hold totals instead.
