Detailed Description

template<class T>
class Table1D< T >

A 1D tabular function interpolated over a grid.

The domain is [a,b]. If values contains n items v0,...,vn-1, then each item vi is reached exactly at x = a+(i+0.5)/n*(b-a) (interpolation through cell centers).

Each cell is "active" over the x range [a+i/n*(b-a),a+(i+1)/n*(b-a)].

Lookup gives the index i and the interpolation value u in [-0.5,0.5] that tells how much to blend an adjacent value at i-1 or i+1.
