alea-weibull Generates a number with a Weilbull distribution. "Generates a number with a Weilbull distribution. The variable s controls the horizontal spread while t controls the actual shape of the distribution; the output has a 99.9% chance that it will fall below 6.9 ^(1/t)*s. When t is 0.5, the function resembles an exponential distribution, and at 3.2 a Gaussian distribution"	from the library : MaxAlea Format : External Environment : max freeware Max 3.x / 4.5 / 4.x ftp://ftp.forumnet.ircam.fr/pub/max http://faia.free.fr/Max_alea/Max-alea_X_2.b1.sit
