To avoid burdening the user with explicit type construction when using
the library, we can use a constructor that accepts an initializer list
(std::initializer_list). This allows users to pass initializer lists
directly without having to wrap them in
std::vector<std::vector<std::string>>. This resolves the ambiguous case
when the inner list contains only two elements.

This implement the flexbox elements, following the HTML one.
Built from them, there is also the following elements:
- `paragraph`
- `paragraphAlignLeft`
- `paragraphAlignRight`
- `paragraphAlignCenter`
- `paragraphAlignJustify`
This is a breaking change.
