normalise function is not a part of pmtk, may be we have to use normalize one instead #32

What steps will reproduce the problem?
1.Some functionality that uses function
path = viterbi_path(prior, transmat, obslik)

What is the expected output? What do you see instead?

What version / revision of the product are you using? On what operating
system?
pmtk r2776

Please provide any additional information below.
Replace normalise function with normalize one on lines: 53, 64

I also experienced this same problem. I don't know if there is a separate 
normalise.m file that is needed, or if changing these lines to "normalize" 
correctly solves the problem. What is more interesting is that this (possible) 
bug causes the testPmtk3 to fail:

??? Undefined function or method 'normalise' for input arguments of type 
'double'.

Error in ==> viterbi_path at 53
    [delta(:,t), n] = normalise(delta(:,t));

Error in ==> hmmMap at 22
path = viterbi_path(pi, A, exp(logB));

Error in ==> hmmDiscreteTest at 38
decodedFromTrueViterbi = hmmMap(trueModel, observed);

Error in ==> testPmtk3 at 68
hmmDiscreteTest;
