Detailed Description

Complex additions to vnl_math.

We don't want everyone to pay for complex when they don't need it, as its ratio of expense to frequency of use is high. So we define those functions from vnl_math which use complex here instead. In a sense, vnl_math should be a namespace, and this file adds to that namespace.
