Locates from a synset id any relevent evocations and constructs an evocations hash.

 @see Synset
 @param [String] senset_id The id number of a specific synset.
 @result [Hash, nil] A hash in the format { 'relations' => ..., 'means' => ..., 'medians' => ... }, or nil if no evocations are available.
 @raise [NoWordnetConnection] If there is currently no wordnet connection.
