Totally rework the math library, this time based on the MacOs X

math library (which is itself based on the math lib from FreeBSD).

-/*							pdtrl.c
- *
- *	Poisson distribution
- *
- *
- *
- * SYNOPSIS:
- *
- * int k;
- * long double m, y, pdtrl();
- *
- * y = pdtrl( k, m );
- *
- *
- *
- * DESCRIPTION:
- *
- * Returns the sum of the first k terms of the Poisson
- * distribution:
- *
- *   k         j
- *   --   -m  m
- *   >   e    --
- *   --       j!
- *  j=0
- *
- * The terms are not summed directly; instead the incomplete
- * gamma integral is employed, according to the relation
- *
- * y = pdtr( k, m ) = igamc( k+1, m ).
- *
- * The arguments must both be positive.
- *
- *
- *
- * ACCURACY:
- *
- * See igamc().

- *
- *
- * SYNOPSIS:

- * int k;

- *
- * DESCRIPTION:
- *
- * Finds the Poisson variable x such that the integral
- * from 0 to x of the Poisson density is equal to the

- *
- * This is accomplished using the inverse gamma integral
