// <synopsis>
// An EvenPolynomial<T> contains a set of coefficients;
// its fundamental operation is evaluating itself at some "x".
// The number of coefficients is the order of the polynomial divided by two,
// plus one, so is the number of available parameters.
//
// </synopsis>
//
// <example>
// <srcblock>
// EvenPolynomial<Float> pf(3); // Second order polynomial - coeffs 0 by default
// pf.setCoefficient(0, 1.0);
// pf[1] = 2.0; // 2x^2 + 1x^0
// pf(2); // == 8
// </srcblock>
// </example>
// <templating arg=T>
// <li> T should have standard numerical operators. Current
// implementation only tested for real types (and their AutoDiffs).
// </templating>
// <thrown>
// <li> Assertion in debug mode if attempt is made to address incorrect
// coefficients
