IFFE setting up the store and merging all n possible ‘script-tags’ into one
```
Scandio.bridge.init = function() {
```

Gets all scripts and sets up the cache for merging

   var
      scripts     = $('.' + Scandio.bridge.identifier),
      tempCache   = null,
      mergeCache  = {};

The main script to be the merge-bucket

   Scandio.bridge.script = $('head #' + Scandio.bridge.identifier);

Respects actually used script-tag having data already

   mergeCache = Scandio.bridge.script.text() !== "" && Scandio.isObject(
      tempCache = Scandio.json.from(
         Scandio.bridge.script.text()
      )
   ) ? tempCache : mergeCache;

Collects each’s script text and merges it into the mergeCache while removing it afterwards

   Scandio.util.each(scripts, function(script) {
      var $script    = $(script);

      Scandio.util.extend(mergeCache, Scandio.json.from( $script.text() ));

      $script.remove();
   });

Updates the merged contents to the main-script

   Scandio.bridge.script.text( Scandio.json.to(mergeCache) );

   return Scandio.bridge.script.length === 1;
};

¶

Gets a value from the script-tag E.g.: Scandio.bridge.get('firms.microsoft', false) might return a company object-literal or false if it is not set
```
Scandio.bridge.get = function(dots, notFound) {
```

Break early if DOM-injection is disabled

   if (injectDOM === false) { Scandio.debug.warn("DOM injection disabled globally, script-tag not present!"); return; }

¶

Parses the data from the script (ran everytime to not run into update-read conflicts)
```
   var storeData = Scandio.json.from( Scandio.bridge.script.text() );
```

Gets the demanded value by dot-notation

   return Scandio.util.getByDots(dots, storeData, notFound);
};

¶

Sets a value on the script-tag *E.g.: Scandio.bridge.set('firms.scandio, {name: 'Scandio GmbH'}) will add the scandio literal to the firms object. It will overwrite an existing entry and fail if firms it not an object but a primitive type.
```
Scandio.bridge.set = function(dots, value) {
```

Break early if DOM-injection is disabled

   if (injectDOM === false) { Scandio.debug.warn("DOM injection disabled globally, script-tag not present!"); return; }

¶

Parses the data from the script (ran everytime to not run into update-read conflicts)
```
   var storeData = Scandio.json.from( Scandio.bridge.script.text() );
```
¶

Sets the value by dot-notation on the retrieved data
```
   Scandio.util.setByDots(dots, value, storeData);
```
¶

while setting it as strinfified JSON on the script-tag afterwards
```
   Scandio.bridge.script.text( Scandio.json.to(storeData) );
```
¶

Returns the value so tmpl/views can pipe it through
```
   return value;
};
```
¶

Global DOM-Ready which shall be used whenever possible Logger does not use it cause it heavily relies on variable hoisting
```
$(function() {
   Scandio.bridge.init();
});
```
