Features suggestion

**Horizontal lateral positions**
- The left and right lateral positions, currently used, are with respect to the center. Extra ones could be added with respect to the left and right vertical sides (like those in [Balloon.css](https://github.com/kazzkiq/balloon.css)). For that purpose, a `reference` attribute with values `side` and `center` could be used. So, each `top-left`, `top-right`, `bottom-left` or `bottom-right` comes together with one of `side` (default) or `center`.

**Size/Width**
- An extra tooltip size/width (`fit`) that equals to the target/element's width (like that in [Balloon.css](https://github.com/kazzkiq/balloon.css)) could be added, too.

**Awesome font**
- Icon fonts to be supported (like those in [Balloon.css](https://github.com/kazzkiq/balloon.css)). `!cool`

**Arrow**
- Support for removing the arrow (like that in [Tootik](https://github.com/eliortabeka/tootik)) `!important`
- Support for other indicators such as `half arrow` (like that in [Simptip](https://github.com/arashmanteghi/simptip)) `!beauty`
