Plot cell-cell similarity in a line graph

1	plot_cell_similarity(x, cell_sim, group.by, DR = "pca", dims = 1, AP = NULL)

`x`	a Seurat object
`cell_sim`	cell similarity matrix of N X M, where N is the sample and M is the cell type. M must be equal to the column number of `x`
`group.by`	which feature to color
`DR`	dimensionality reduction assays in `x`
`dims`	which dimension to plot along the x axis
`aes_param`	aesthetic parameters passing to `theme_TB`
