(require src/leaflet-search.css)

Adding the search control to the map:
`javascript
var searchLayer = L.layerGroup().addTo(map);
//... adding data in searchLayer ...
map.addControl( new L.Control.Search({layer: searchLayer}) );
//searchLayer is a L.LayerGroup contains searched markers
`

Short way:
`javascript
var searchLayer = L.geoJson().addTo(map);
//... adding data in searchLayer ...
L.map('map', { searchControl: {layer: searchLayer} });
`

AMD module:
`javascript
require(["leaflet", "leafletSearch"],function(L, LeafletSearch) {

//... initialize leaflet map and dataLayer ...

map.addControl( new LeafletSearch({
layer: dataLayer
}) );
});
`

Build

Therefore the deployment require npm installed in your system.
`bash
npm install
