Suppose you are drawing "lines" in the terminal using
box-drawing characters and are filling in a 2-D grid of chars.
You might first put down a ┌ but then later want to draw a ┴ on top of that. This crate will calculate that the resulting char should be a ┼.
You can also convert a 4-bit bit string into a line drawing character.
```rust let combo = unicodelinestacker::stack('┌', '┴'); assert_eq!(Some('┼'), combo);
// Bit string format: for each of the four directions, clockwise starting from // top (least significant to most significant), 1 means "on" and 0 means "off." let c = unicodelinestacker::bitstochar(0b1011); assert_eq!('┴', c); ```
Right now the crate only supports the "light" line drawing characters in the four cardinal directions.
