Refactored AttributeExtractor to be a @Bean
#72 Fixed issued with linking Bean with IDataStore
#72 added support to check ScoredAttribute's main type, according to a
threshold currently set a 0.8.
#72 commented out code that was not useful anymore in parts that I
didn't write and put a todo so that the owners would know to fix it.
#72 Merge branch 'master' into Issue72
