Function which can be used to draw simple, but also specialized boxplots.
For example :
1) Horizontal boxplots
2) Grouped boxplots
3) Use a different y axis for each boxplots
4) Ignore empty boxplots
5) Display the mean value over the boxplot, and customize it
6) Change the definition of outliers. Can be the inter-quartile range or the standard deviation (and different multipliers).
7) Modify the width of boxplots
8) Specify the "x-position" of each boxplots. Please note that this may cause some aesthetic problems in certain cases. This also works if the direction is horizontal, but then it will correspond to the y-position
9) Combine all of the above
Data inputs can be vectors, matrixes or cells
Colors (edges, filling, outliers) can be customized
This function use the "quantile" function from the statistical toolbox. If not available, I recommend you download the "Quantiles" function by David Ferreira (https://www.mathworks.com/matlabcentral/fileexchange/70279-quantiles) and place it in your directory
