function [ segment,TerrainFile,xs,ys,xe,ye,nwp,wp ] = getProjectInput( filename )
%This function should be called getProjectInput and take a single
%input, the project file name, project.ini. It should have multiple outputs which are: TerrainFile, StartPoint,
%EndPoint, NumWayPoints, and WayPoints (if NumWayPoints is greater than zero). StartPoint and
%EndPoint should be a 1x2 or 2x1 vector. WayPoints should be a NumWayPoints x 2 or 2 x
%NumWayPoints matrix.
