Comment lines are also enhanced.
1.0.2.0

function renames as ispermsdisjoint
function returns '1' if the permutations are disjoint, otherwise returns '0' (string output is removed)
for loop is removed and replaced with 'any(x==sigma1 & x==sigma2)'
1.0.1.5

included a check for validity of the permutations sigma1, sigma2, small letter 'l' is replaced with capital letter 'L',
