CONSTANTS
There are a few constants known to the special function package, namely
_ _ _ Euler's constant (which can be computed as - Psi(1)) and
_ _ _ Khinchin's constant (which is defined in Khinchin's book ``Continued Fractions'') and
_ _ _ Golden_Ratio (which can be computed as (1 + sqrt 5)/2) and
_ _ _ Catalan's constant (which is known as an infinite sum of recipro cal powers)
