/**
* To create an overlay you just need to create a JSON file.
* The styles defined in the styles are cascading, meaning that
* the styles can be defined on the top level, or directly at the
* single items. If the style is not defined in the item, the top-level style will be used.
* If the top-level style is not defined either, the default style is applied.
*
* The structure of an overlay file is as follows:
*
* {
* //COMMENT: Top-Level
*
* //COMMENT: Frequently used properties are:
* size: 500,
* color: 0xFF00FF,
* fillAlpha:0.5
*

* //COMMENT: Items are defined in the items array.
* {
* location: {
* //COMMENT: Location must be defined.
