Title: Package restructure, Ring without Eq, and nroots in Numeric.

This splits spire.math into 2 packages: spire.math and spire.algebra. The former is a focused numerics package, while the latter is general abstract algebra. This also removes Eq from Ring and adds NRoot to Numeric and Fractional (and so removes NumericWithNRoot and FractionalWithNRoot).
