A simple uncompleted package to draw flat banners
For this package to work, you need to define a color named mainColor:
\usepackage{xcolor}
\definecolor{mainColor}{RGB}{211, 47, 47}
For now, it only defines one command: \yBanner[<Banner minimum width>][<Banner endings vertical drop>][Banner endings outer width][Banner endings inner width]{<Banner text>}.
