stretch(a, size) : Stretches a value or a range and returns a vector
Explanation :
If a is a single value (or a vector with a single item), the
function returns a vector with "size" items containing that value
stretch(0, 12) = {0,0,0,0,0,0,0,0,0,0,0,0}
After that, you could do :
set(stretch(0, 12), 1, time%12)
This returns:
{1,0,0,0,0,0,0,0,0,0,0,0} when time<1
{0,1,0,0,0,0,0,0,0,0,0,0} when time<2
{0,0,1,0,0,0,0,0,0,0,0,0} when time<3
etc.
If a is a vector with more than one value, the function stretches
the range over "size" items :
stretch({1,4}, 4} = {1,2,3,4}
stretch({0,10},11} = {0,1,2,3,4,5,6,7,8,9,10,11}
sumof(a) : Sums all the items of an array
