A class for performing search actions. The class takes a view context and search string as parameters. The search string can be either (a) a feature (e.g. gene), or (b) a locus string in the UCSC form, e.g. chr1:100,000-200,000
Note: Currently the only recognized features are genes
Custom searchers can be registered, see {@link #registerNamedFeatureSearcher(org.broad.igv.dev.api.NamedFeatureSearcher)}
