INC_GAMMA_MAX_ITERATIONS

The maximum number of iterations permitted for the incomplete gamma function evaluation process.

Defined as DEFAULT_MAX_ITERATIONS rather than as its own number. The two govern the same series reached by different routes -- this one through the static entry points, the other through an instance's maxNumIterations -- so allowing them to differ means a direct call to incompleteGammaFunction can throw on a shape that an instance of this class evaluates without complaint. They were independently set to 5000 and are now tied together so they cannot drift apart again.
