//  LineView.h
//
//  Created by Tyler Neylon on 4/5/11.
//
//  View to draw a single line.
//
//  Sample usage:
//
//    CGPoint a = CGPointMake(10, 10);
//    CGPoint b = CGPointMake(50, 100);
//    LineView *lineView = [LineView lineFromPoint:a toPoint:b];
//    lineView.color = [UIColor blueColor];
//    [self.view addSubview:lineView];
//

#import <Foundation/Foundation.h>
