Made changes to a number of files. The changes are summarised below:
1) ASSL Analyse syllables - added a provision to choose a syllable and
plot its spectrogram and amplitude profile. Also, fixed the display
syllable details - modified the algorithm that looks for the syllable
once a syllable has been picked. Right now, am using knnsearch to find
the nearest neighbour to the point chosen in the graph.
2) Wrote a mex file to calculate variance for fisher threshold to speed
it up.
3) Made some other changes to some other files that are part of
