              FoldCurve

Child of Continuation class that represents curves of limit
points.

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

        A = f_{x}(x,a)

    (see class PyCont.TestFunc.BorderMethod)
    (see class PyCont.TestFunc.Fold_Bor)

    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
                 { G(x,a) = 0

Detection of points: BT, ZH, CP (BP points not currently
implemented).
