Added sentiment, updates to analytics

Added

• We added sentiment, which can now be used in querying of articles and events. The QueryArticles, QueryArticlesIter, QueryEvents, QueryEventsIter constructors now all have additional parameters minSentiment and maxSentiment that can be used to filter the articles and events. The valid values are between -1 (very negative sentiment) and 1 (very positive sentiment). Value 0 represents neutral sentiment.
• Sentiment was also added as a property in the returned articles and events.

Updated

• Analytics: We updated trainTopicOnTweets(), trainTopicClearTopic() and trainTopicGetTrainedTopic() methods in the Analytics class.
• Analytics.annotate() method now supports passing custom parameters that should be used when annotating the text.
• Changed some defaults in the returned data. When searching articles, we now by default return article image and sentiment.
• Analytics. updated trainTopicOnTweets(), trainTopicClearTopic() and trainTopicGetTrainedTopic() methods in the Analytics class.
• QueryArticles.initWithComplexQuery() was updated - the parameter dataType was removed (since the dataType value should be provided in the $filter section of the query)
• TopicPage now supports setting also the source rank percentile
• Analytics.extractArticleInfo now also supports setting the headers and cookies to be used when making the requests
