              HopfCurveOne

Child of Continuation class that represents curves of Hopf
points.

Augmented system h(x,a): Uses double bordering on the matrix A
given by

        A = 2*f_{x}(x,a) (*) I

    where (*) denotes the bi-alternate matrix product.

    (see class PyCont.TestFunc.BiAltMethod)
    (see class PyCont.TestFunc.BorderMethod)
    (see class PyCont.TestFunc.Hopf_Double_Bor_One)

    The continuation variables are (x,a) with

        x = State variables
        a = Free parameters

    and the continuation curve is defined by

        h(x,a) = { f(x,a) = 0
                 { det(G) = 0

Detection of points: BT, ZH, GH, DH
