Detailed Description

template<int PolySize>
class Foam::Polynomial< PolySize >

Polynomial templated on size (order):

poly = sum(coeff_[i]*x^i) logCoeff*log(x)

where 0 <= i <= N

integer powers, starting at zero
value(x) to evaluate the poly for a given value
derivative(x) returns derivative at value
integral(x1, x2) returns integral between two scalar values
integral() to return a new, integral coeff polynomial
- increases the size (order)
integralMinus1() to return a new, integral coeff polynomial where the base poly starts at order -1
