love the package, question about the multiple categories!

[mjstrumillo]

HI, package works great for one condition, but for two I was getting a bug - I worked around it by manually connecting the obs columns into one adata.obs["one_two"] = adata.obs["one"].astype(str) +"_" +adata.obs["two"].astype(str)

but maybe its something that can be done in the code if you need it? since I think that the dtype was somehow messing the multiple category function. thanks! MJ
