Merge branch 'development' of https://github.com/University-of-Potsdam-MM/contactJS into development

# Via Helena Jank (1) and hjank (1)
* 'development' of https://github.com/University-of-Potsdam-MM/contactJS:
  Update README.md
  # adjusted README to latest changes in components: inOut -> description, updateInterval
  # completed README, added contents

! [Discoverer] fixed a bug where Interpreters wouldn't searched for when a Widget was found that satisfies an attribute
! [Aggregator] fixed a bug where Interpretations would be called multiple time if a Widget returned more than one required attribute

Merge branch 'development' of https://github.com/University-of-Potsdam-MM/contactJS into development

+ [Aggregator] when receiving data from a Widget, Aggregators now search for an Interpretation in need for that information and will query the associated Interpreter
+ [Aggregator] queryReferencedInterpretation(theInterpretation, callback)
# [Widget, Interpreter] the static variable for the description of the component is now "description" (duh!) and not "inOut"
# [Widget] the description object now holds a variable "updateInterval"; it defines the update interval in milliseconds
# [Widget] if an update interval is given in the description the Widget will call its queryGenerator() method regularly
# updated some log messages
# updated some instance checks

# [Component] added more shared functionality from Widget, Aggregator and Interpreter

# [Aggregator] changed database initialization

+ [Component] added Component as superclass of all classes that are managed by the discoverer; duplicate functionality from Widget, Aggregator and Interpreter will be outsourced into Component in the future
+ [Component] Components and subclasses can use this.log() the create meaningful log messages referencing themselves
# [Storage] the constructor of Storage accepts a fourth parameter which is a reference to the Aggregator that created the Storage (is used for logging purposes)
# [Widget] the constructor won't override the name attribute if it's been already set
! [Widget] fixed a bug in addOutAttribute() where existing attributes were not updated with new values
+ added a new unit test for the translation functionality of the the discoverer

+ [AttributeList] fromAttributeNames(discoverer, attributeNames)
+ [AttributeList] putIfTypeNotContained(attribute)
+ [AttributeList] _getAttributeWithName(attributeName)
+ [Discoverer] getPossibleAttributes()
+ [Discoverer] getAttributeNames(attributeNames)
+ [Parameter] added data type and updated methodes accordingly
# [AttributeList] fromAttributeDescription -> fromAttributeDescriptions
# [Discoverer] buildAttribute(name, type, parameterList, withSynonyms) -> buildAttributes(attributeName, attributeType, parameterList, withSynonyms)

# [Widget] updated attribute initialization to use the new static construction method of AttributeList

+ [AttributeList] added a static method to create an AttributeList from the description provided by a Widget or Interpreter
- [Widget] removed obsolete elements from the attribute description
# [Discoverer] updated to make use of AttributeList.fromAttributeDescription()

* rueger/development:
  # some more clean up
