Text object

Nadie ha tomado este issue todavía.

Design a Text object that allows you to set its size, color, and value. Its most important feature is to retrieve the text width and height so that developers can check whether they fit in a given region. For example, the feature allows you to check whether the text could fit inside a box of a given height and width.

A possible solution would be to create an image object, drawtext on it, then retrieve the objects resulting width and height as described [here](https://stackoverflow.com/questions/24190327/getting-the-dimensions-of-a-rendered-text-in-cimg-library). The suggested code is shown below for reference:

```cpp
CImg imgtext;
unsigned char color = 1;
imgtext.draw_text(0,0,"Hello guys !",&color,0,1,23); // Draw with font height 23.
// Now, imgtext.width() and imgtext.height() gives you the dimensions you want.
```

Comience con el ejemplo vinculado de CImg draw_text y determine cómo debería exponer un objeto Text size, color, value y las dimensiones renderizadas. Se considera terminado cuando los desarrolladores pueden establecer esas propiedades y recuperar width y height para comprobar si el texto cabe en una región especificada.
