Graphics layer and configureability nhancements:

Formatting

I was using the cmv eslint settings, so everything got reformatted. If you don't want to accept this due to the formatting changes, its completely understandable, but you should at least be able to see the changes in this commit:

https://github.com/BrianBunker/cmv-widgets/pull/44/commits/8690d6741154920f95d7dda59c3feabd9a6386b9

add a graphics layer for coordinates that are found

When the user searches, a map icon is displayed using the maps graphics layer

separate coordtypes into a different file

Cleans up the widget a bit as all the coordinate system transformation code lives in CoordTypes.js

ability to set default values for the textbox and add custom coordinate systems

Prepopulate the textbox with a shortened version of a coordinate, for example mgrs, we can provide the grid zone for a local area.

A sample config file for providing cusotm projections might look like this:

goto.js:

define([
    'proj4js/proj4',
    'dojo/topic'
], function (proj4, topic) {
    var mnrice = 'PROJCS["Rice County MN",GEOGCS["Rice County Datum",DATUM["<custom>",SPHEROID["<custom>",6378434.181,298.2572256054303]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Lambert_Conformal_Conic"],PARAMETER["False_Easting",500000.0],PARAMETER["False_Northing",100000.0],PARAMETER["Central_Meridian",-93.13333333333334],PARAMETER["Standard_Parallel_1",44.3],PARAMETER["Standard_Parallel_2",44.66666666666666],PARAMETER["Latitude_Of_Origin",44.1947221],UNIT["Foot_US",0.3048006096012192]]';
    var wgs84 = proj4.defs('WGS84');
    return {
        map: true,
        coordTypes: [{
            id: 'ricemn',
            label: 'Rice County Coordinates',
            examples: ['463993.5101,135233.3642'],
            helpText: 'The input accepts two coordinates (easting, northing) separated by a comma.',
            toLatLong: function (input) {
                var coords = input.replace(/[A-Za-z$-]/g, '').split(',');
                if (!coords.length === 2) {
                    topic.publish('growler/growl', {
                        title: 'Format not valid',
                        message: 'Please enter the coordinates like the example: easting,northing OR 12344.1234,12344.1234'
                    });
                }
                return proj4(mnrice, wgs84, coords);
            }
        }]
    };
});

and viewer.js:


        coordinates: {
            title: '<i class="fa fa-crosshairs"></i> Find Coordinates',
            include: true,
            id: 'coordinates',
            type: 'titlePane',
            path: 'brianbunker/Goto/Goto',
            open: false,
            position: 7,
            options: 'config/viewer/goto'
        },

Proj4 location

Proj4 path now points to proj4js/proj4 to use the configured proj4 from the dojo config file.
