Setup Transmission type Optical Element similar to the one simulating CRL, but with arbitrary optical path in material over hor. and vert. positions, defined by external function _func_path(x, y) :param _func_path: user-defined function of 2 variables specifying path in material over hor. and vert. positions (x, y) :param _delta: refractive index decrement (can be one number of array vs photon energy) :param _atten_len: attenuation length [m] (can be one number of array vs photon energy) :param _rx: horizontal aperture (range) size [m] :param _ry: vertical aperture (range) size [m] :param _xc: horizontal coordinate of center [m] :param _yc: vertical coordinate of center [m] :param _ext_tr: transmission outside the grid/mesh is zero (0), or it is same as on boundary (1) :param _fx: horizontal focal length [m]; if it is not set, a numerical estimate will be made (around _xc, _yc) :param _fy: vertical focal length [m]; if it is not set, a numerical estimate will be made (around _xc, _yc) :param _e_start: initial photon energy :param _e_fin: final photon energy :param _nx: number of points vs horizontal position to represent the transmission element :param _ny: number of points vs vertical position to represent the transmission element :return: transmission (SRWLOptT) type optical element which simulates CRL
