Super slow -- probable rewrite?

[mxtlrr]

Yeah. Even though treng has gone through a rewrite from C++ to JavaScript, the JavaScript rewrite is actually slower!	Computing Function	C++ Time	JavaScript Time
$f(2,4)$	~0.2-0.4s	30s - 3 min
$f(2,5)$	~0.6-0.8s	1-4 min
$f(2,6)$	N/A	>1 hr

Obviously, the data shows that JS may not be the perfect language for this. However, this also may be due to unoptimized functions (#1), but it also may be that string operations where the length of the string $n$ is $> 10^{50}$ digits. This issue is only here to document a potential rewrite / optimizations of other functions that do not fit into pre-existing issues.

$f(2,5)$ was computed in 113s while $f(2,4)$ was computed in 0.29s. From other tests, it seems like BOTH operations are slow!

Operation	Time
$\sum_{n=1}^{50}{2}$	~0.36s
$\prod_{n=1}^{50}{2}$	~0.21s

Sadly, javascript is not really multithreaded -- this means we might have to go back to our roots in C++.

An updated table of JS rewrite's timing function (lowest was taken):	Function $f$	Time
$f(2,1)$	0.1559s
$f(2,2)$	0.0179s
$f(2,3)$	0.0090s
$f(2,4)$	0.2699s
$f(2,5)$	69.401s
$f(2,6)$	Unknown $^1$

$^1$: $f(2,6)$ has never been computed with treng yet.
