Given a polynomial f(x) of degree n expressed as a row vector of coefficients of x^k with
highest power on the left, expand f(x) as a sum of scalar multiples of
Chebyshev polynomials, i.e. return the column vector of coefficients a_k with k
running from n to 0 from top to bottom such that f(x) = sum_{k=0}^n{a_k P_k(x)}.
