The program should include a function generalInterpolation(fs,xs) that finds the
interpolating polynomial including in cases where there are repeated points (inlcuding Hermite interpolation, where the points are doubled, and Taylor series, where all
nodes are in the same location). It should do this by constructing a divided difference table, then returning the polynomial defined by the table and the interpolating
nodes xs
