// <synopsis>
// A SPolynomial<T> contains a set of coefficients; its fundamental operations
// is evaluating itself at some "x". The number of coefficients is the order
// of the polynomial plus one, plus an additional 3 as height, center, width.
//
// </synopsis>
//
// <example>
// <srcblock>
// SPolynomial<Float> pf(3); // Third order polynomial - coeffs 0 by default
// pf.setCoefficient(1, 1.0);
// pf[5] = 2.0;
// pf.setCoefficient(3, 3.0); // 3x^3 + 2x^2 + x
// pf(2); // == 34
// </srcblock>
// </example>
// <templating arg=T>
// <li> T should have standard numerical operators. Current
// implementation only tested for real types (and their AutoDiffs).
// </templating>

// coefficients
