 The results:
 
 Polynomial.roots:         15.80 microseconds/call  1.0x

 Python (Analytical):       1.77 microseconds/call  8.92x
+
 Rust-Python (Analytical):  0.37 microseconds/call  46.47x
 
 On some quick-and-dirty benchmarks, our analytical implementation improved almost 9x over Polynomial.roots(), and our Rust implementation was nearly 7x faster *again* on top of that, nearly 50x faster than the original.
