public static boolean lineContains(double[] endpointOne,
                                   double[] endpointTwo,
                                   RealLocalizable testPoint,
                                   int dims)
```
    Tests if the point given point is on a line.
    
    Parameters:
    
    endpointOne - Line segment endpoint
    
    endpointTwo - Line segment endpoint
    
    testPoint - Point to test
  - pnpoly
```
public static boolean pnpoly(gnu.trove.list.array.TDoubleArrayList x,
                             gnu.trove.list.array.TDoubleArrayList y,
                             RealLocalizable localizable)
```
    Return true if the given point is contained inside the boundary. See: https://wrf.ecse.rpi.edu/Research/Short_Notes/pnpoly.html

public static RealInterval getBoundsReal(Collection<? extends RealLocalizable> vertices)

  - getBoundsReal
```
public static RealInterval getBoundsReal(double[][] vertices)
```
    Finds the smallest RealInterval which contains all vertices.
    
    Parameters:
    
    vertices - A 2D array containing all the vertices, where the first index indicates the vertex and the second indicates the dimension. So vertices[ 0 ][ 2 ] is the value of the first vertex in the third dimension.
    
    Returns:
    
    A RealInterval which contains all the vertices
  - getBoundsReal
```
public static RealInterval getBoundsReal(double[] x,
                                         double[] y)
```
    Finds the smallest RealInterval which contains all x, y coordinates. If the x and y arrays are not equal in length the larger array will be truncated.
    
    Parameters:
    
    x - x coordinates of the vertices
    
    y - y coordinates of the vertices
    
    Returns:
    
    A RealInterval which contains all the vertices
