Figure out the scope of the program, what it does, what it doesn't do, etc.

[absolom]

This program will take a set of instructions which define a block diagram and then generate an ASCII representation of that block diagram.

Features

• Blocks can have text inside them.
• Blocks can be connected by lines.
• Lines can have arrows at their ends.
• Lines can have text associated with them OR an interface line and text.

Major Pieces

• Algorithm to render lines between boxes.
• Algorithm to place line text near lines.
• Algorithm to place boxes so lines and line text overlap as little as possible.
• Algorithm to create boxes around text.

    |Box Text|4            |Another box's text
        1                         a

                 >1 a4
            |Multiline Box

Should produce

    ┌────────┐             ┌──────────────────┐
    │Box Text├─────┐       │Another box's text│
    └────┬───┘     │       └────────┬─────────┘
         └────►───┐├────────────────┘
            ┌─────┴┴──────┐
            │Multiline Box│
            └─────────────┘
