#337 Fixed mapping loader that was missing mappings. There was a totally incorrect comparison occurring.
#336 Fixed mappings behavior when bad data that is missing an endpoint is returned.
#335 Have sliders working for D3 ontology view, so that we can filter out arcs and nodes on the basis of their size, on a percentile scale. There is some glitchiness with the sliders themselves, and the way the panel itneracts with the mouse may be reconsidered. Also, using percentiles leads to horribly uncontrolled jumps. Perhaps we can use absolute counts, ordered by their size?
#335 Sliders less glitchy now, and got rid of transparency in hovering menu. Still considering other options that percentile filtering, such as sorted count filtering instead.
