Add Visualization Examples

[ducku]

I included some chunks created from prepare_local_chunks. However, it seems that some haplotypes are added that didn't exist in the original. Not too sure what causes this. I added the original files in a visualization_exmaples folder.

Here are some pictures:
chr7_124051614_124054114__HCC1395_ref0_500-1500:

chr1_86645908_86646408_chr1_1-500:

chr5_73149742_73150242_ch5-1-500:

I think the extra haplotypes are coming in because, if you view the GBZ with the tube map it runs vg chunk on it and deduplicates locally identical haplotype paths. But if you use prepare_local_chunk.sh (and not prepare_chunks.sh) it runs it through vg convert and all the haplotypes in the graph become their own paths, even if they are locally identical.

I'm re-pulling the chunks by running:

cd exampleData

rm -Rf lancet_chunk_example_*
rm -f lancet_chunk_examples.bed

This I think gets us the right coordinates in the genome displayed, given the apparent start coordinates of the subgraphs being extracted from. It also gets us about the result of actually loading up the source subgraphs and requesting the specified regions.
