add ability to search for gene(s) in current view about gcv HOT 3 OPEN

adf-ncgr notes to self that this issue has some conceptual overlap with the hack that he put in a local version of the legend.js code to aid in evaluating FrequentedRegions algorithm results, something along these lines in the on mouseover associated function with elements generated in the legend _drawKey method; Hopefully, if we ever actually address this issue, it will be through something far less hacky and involving breakpoints and injection of state via the console!
selection[0] = [];
var fs=['phytozome_10_2.59205044','phytozome_10_2.59028006','phytozome_10_2.59315123','phytozome_10_2.59271012','phytozome_10_2.59073169','phytozome_10_2.59179688','phytozome_10_2.59310457','phytozome_10_2.59227160'];
fs.map(f => {selection[0].push.apply(selection[0], d3.selectAll('.GCV [data-family="'+f+'"]')[0])});

@adf-ncgr Since the gene that you would be searching for would only be present in the micro-synteny viewer, does it make sense to repurpose the existing search widget for this purpose and add a new search widget to the main navbar at the top for providing a new focus gene?

I recently hacked a primitive version of this into GCV for @adf-ncgr, which made me recall this issue. Here are some implementation details that came to mind when implementing the hack:

• This should be a top-level feature that applies to all micro-synteny viewers in the view, e.g. add a highlight icon to the top-level navbar
• Clicking on the highlight icon should open a widget that allows users to toggle between highlighting the query genes and genes that they enter manually into a text field
• The genes entered in the text field should persist between pages but not be encoded in the URL like other parameters due to URL query string length limitations (persistence should be implemented via NgRX/store)
• Extra credit: the highlight widget could include a color selector that allows users to select what color they want to highlight genes with as an alternative to the default black color, which can make it hard to spot highlighted genes
