make_legend: Extract Figure Legend from Individual Plots for Later...
In chenyenchung/PlotSeurat: Plots That You Might Also Want With Seurat

Since ggplot2 does not support superimposing multiple geom_point() with different color codes, MultiFeaturePlot() bypasses the limitation by generating one custom color scale integrating multiple expression data. To get legends for that, individual geom_point() ggplots are generated here, and extracted for later integration with the main plot.

1	make_legend(featurekey, plotdf)

`featurekey`	a character vector containing the features prefixed by keys (if using Seuratv3) to be plotted
`plotdf`	a data frame containing cell embedings, expression level, and color codes genearted by `bin_expression()`

a ggplot2 object
