Tips)

You can customize map file with .cub extensions.
- The map file requires:
  - Screen Resolution
```
R 640 640
```
  - Texture File paths
```
NO ./textures/north.xpm
SO ./textures/south.xpm
EA ./textures/east.xpm
WE ./textures/west.xpm
```
  - Sprite File path
```
S ./textures/sprite.xpm
```
  - The texture, sprite file must be .xpm extension.
  - Floor and Ceiling Color in RGB Format
```
F 0,200,100
C 0,220,130
```
  - Map structure
```
1111111111
1110000001
1000000111
11N0000021
1111111111
```
    - 0 means empty spot, 1 means wall, and 2 means sprite location.
    - The NSWE mean player's spawning directions.
    - The map has to be 'closed'.
- If you run the program with invalid formatted map file, it will occur errors.

The goal of cub3d is to make something using raycast like Wolfenstein 3D, or Doom.

Must use the miniLibX: Library for Graphic Activity in C (OpenGL or MMS based)
Textured Wall Needed
Display a item (sprite)
The left and right arrow keys of the keyboard must allow you to look left and right in the maze.
Map File Parsing Required
