This service directly calls methods in the google maps javascript included in the darkswarm layout. If we're moving away from it, we should clarify where it's used.
The map is displayed using https://leafletjs.com/
To enable Open Street Map go to the Admin -> Configuration -> Content section and click 'Open Street Map Enabled'.
The 'Open Street Map Provider Name' setting can be used to configure different tile providers thanks to the Leaflet-providers extension (https://github.com/leaflet-extras/leaflet-providers)
Some tile providers require an API key, this can provided in JSON format e.g. '{ apiKey: 123 }' in the 'Open Street Map Provider Options' setting.
Each tile provider has their own usage policy so this should be checked before enabling Open Street Map.
The search field for the Open Street Map works differently than searching on Google Maps. It matches producers by their name or address because it was easier to implement instead of matching place names all over the world.
Here we need to build a really dynamic structure on the page like "Results for: <search-term> in <filter1> or <filter2>" and the styling on each of the words needs to be a bit different, specifically the filter terms need to be differently styled to the join words like "in" and "or". We have to generate those bits on the Angular side, but they also have to be wrapped in HTML in a specific way.
$sce.trustAsHtml() marks the injected HTML as "safe" (in relation to security issues like XSS). In this case the injected content doesn't involve any user-defined data, so it should be fine.
Changes:
* Introduced a cluster marker to denote multiple points of interest at
the same location
* Seperated out a plain enterprise modal into 2 parts
* A modal called EnterpriseModal for showing a list of enterprises at
the same location
* A box called EnterpriseBox(which by the way is also a technically a
modal) that shows the details of that particular enterprise selected
* If at a location there exists only a single enterprise then only the
box is shown
When loading the page $watchGroup calls the listener function for every
listed line item but with a set variant and null quantity and
max_quantity. There's no point on computing an order change when there
was none.
This saves an empty request on the second most used endpoint of the app,
specially busy when users are placing orders.
