hist_fancy: Make a pretty Multiple Histogram
In InfProbSciX/PeRLib: Personal R Library

hist_fancy Extends the hist() function by using ggplot2 for making a pretty histogram. The function calls ggplot2::qplot to make multiple histograms, so arguments will be the same as the hist or the qplot. A qplot object is returned so it's possible to add geoms to it.

`...`	Other arguments for the qplot, such as xlim, ylim, xlab, ylab, main, etc.
`Named_Vectors`	Each vector is used to draw a multiple histogram with each label matching the corresponding vector name.
`Unnamed_Vectors`	are named xnumber.
`fill`	Optional character vector specifying fill colours, as large as the number of vectors fed into the function.
