Request: Ability to render multiple instances of same chromosome

[bradwbradw]

Currently, the DOM element is hardcoded with an ID that depends on the species and chromosome. It would be useful to be able to customize the ID so that multiple views of the same chromosome can show alternative annotations, bands, etc.

I cannot show the same chromosome twice in the same Ideogram object ( Error: Duplicate chromosomes detected.)

I also cannot show the same chromosome twice using two Ideogram instances, because of the hardcoded DOM ID collision issue
