extract_point_direction(data_x, data_y) Extract the direction each point faces.
  Parameters:
    data_x: float array, points x value.
    data_y: float array, points y value.
  Returns: float array.

find_corners(data_x, data_y, rate) ...
  Parameters:
    data_x: float array, points x value.
    data_y: float array, points y value.
    rate: float, minimum threshold rate of data y stdev.
  Returns: tuple with 2 float arrays.

grid_coordinates(data_x, data_y, m_size) transforms points data to a constrained sized matrix format.
  Parameters:
    data_x: float array, points x value.
    data_y: float array, points y value.
    m_size: int, default=10, size of the matrix.
