  * A project configuration may hold the configuration for one or several project
  * directories as well as a general simulator configuration.
- * 
+ *
  * The configuration for a project directory may for example consist of which
  * plugins, interfaces and processes that the specific project directory supplies.
  * Each project directory configuration is read from the property file cooja.config, a
  * file which is required in each project directory.
- * 
+ *
  * Values can be fetched as String, Boolean, Integer, Double or String array.
- * 
+ *
  * Several configurations can be merged, together forming a final overall
  * configuration. The order of the how configurations are merged matter - later
  * values will overwrite earlier. For example merging two configurations with
  * the key 'SOMEKEY' in the following order:
- * 
+ *
  * SOMEKEY = a b c
- * 
+ *
  * SOMEKEY = d e
- * 
+ *
  * will result in the final value "d e".
- * 
+ *
  * If a specific value should be extended instead of overwritten, the value must
  * start with a single space-surrounded '+'. For example, merging two
  * configurations with the key as above in the following order:
- * 
+ *
  * SOMEKEY = a b c
- * 
+ *
  * SOMEKEY = + d e
- * 
+ *
  * will result in the final value "a b c d e".
- * 
+ *
  * The simulator will hold a merged project configuration, depending on which
  * project directories are used. Additionally. each mote type may also have a
  * configuration of its own, that differs from the general simulator
  * configuration.
- * 
+ *
  * Often, but not necessarily, keys are named depending on which class is
  * associated with the information. For example, let's say a battery interface
  * wants to store its initial capacity (a double) using this approach. Data
  * stored in the external configuration file can look like the following:
  * se.sics.cooja.interfaces.Battery.initial_capacity 54.123321
- * 
+ *
  * This value is then be read by: myMoteTypeConfig.getDoubleValue(Battery.class,
  * "initial_capacity");
