input scRNA-seq data, logo, make wording more general

[thereidfleish]

1. Adds the ability to input scRNA-seq data into the Appyter
2. Add logo
3. Update wording to make the Appyter's function more broad (e.g., not just tumors)

hmm...i guess we could call it "foreground"? i don't really like that but i guess it's consistent with "background"... or we could call them "expression vectors" like you say on the configuration page...

lmk what you think, and then i'll make a new commit with the new version number and any name changes we decide to make

I guess input is fine.. feel free to just up the minor patch version, in any-case I likely won't merge this till after next week as to not sabotage someones' demo :smiling_face_with_tear:
