Feature/hearing maps images

What kind of tests could I add to the leaflet directive?

Should I use another kind of name for the directive? something like "locationMap", "addLocationMap", "renderLocationMap" ?¿?
and this would be then
`<location-map latitude="60.17" longitude="24.95" polygon="60.168,24.947 60.173,24.947 60.168,24.952"></location-map>`
