Gene list - graph of chromosomes

[davmlaw]

On the view_genomic_intervals page, it automatically loads a graph of ChromosomeIntervalsGraph. This should be put in a "graphs" tab and only loaded on show, like on the sample page

There should be a new "graphs" tab on the gene list page.

This should load a new chromosomes graph, which takes the gene list, looks up the coordinates (just always use GRCh38 as it's all close enough between builds) and then shows the genes next to the coordinates

The genes on the "-" strand should be on the left written in blue and the genes on "+" strand should be on the right in red. You may need to spread the chromosomes out a lot to give more space

The initial version didn't look any good. The design of the graph someone else had was much better for this purpose.

The key changes were:

• The chromosomes are arranged vertically - this allows the gene names to be written horizontally next to their position
• There is no axis, just a simple label of "1", "X", "Y" etc below the chromosomes
• There should be multiple rows - their graph has chroms 1-8 on row 1, 9-16 on row 2 and 17-22 + X+Y on row 3
• There is a dashed line on each row, and chromosomes are veritically aligned at their centromere to this line
• The banding patterns are simplified
