Vision tiling (#1028)

* showing tents as triangles

* cleanup

* further cleanup ahead of highlight exon to splice implementation

* hovering individual exons highlights that exon

* highlight tent by exon - but I think there are still problems

* improving two way highlighting. still bugs to work out

* let's try tiling the exons within a row

* need to demo vision progress, saving

* tiling appears to be working

* streamlining the way visual mapping is done

* visual tiling is ok but highlighting is weird

* track depth only as deep as needed

* notes to self

* X axis being rendered; need to clean it up

* axis displaying correct numbers

* visual distinction between labels and axis

* ready to try moving the axis to the top

* axis looks good, need tiny cleanup items

* X axis along top looks good

* button labeling

* lines, no dots yet

* dots on top of lines

* dots color coded

* taller tents

* hover tents works on dots only

* explanatory text at top of plot

* styling the diagrams

* colorblind safe color scheme

* strand label

* highlighting chosen item
