location from JSON file

[lioska]

Sorry if my issue is not issue, but in your Wiki no explanation how to create an external JSON file to locate Locations.
In Options ( https://github.com/vdw/MapIt/wiki/Options ) you explain what each name means and how to describe them. But personally I missed how to describe locations if I want to use external file.

To call location JSON file need write
locations: 'locations.json',
?
How must lokks like JSON file?
{{

longitude : 14.141414,
image : 'css/point.png',
....
},
{
latitude : 21,21524,
.....
}
}
