28 * hard-coded subset is used (for the applet, or testing), or
29 * setSequenceOntology() can be used to set full Ontology data.

37 * Answers an instance of this class for the current application context. Note
38 * that this supports running two JS 'applets' on the same page, one with the
39 * full Sequence Ontology (USE_FULL_SO = true) and one with a hard-coded
40 * subset (USE_FULL_SO = false). If this is overkill, could change this method
41 * to just return a common static instance.
