Adding eclipse nature to support eclipse environment with gradle sts plugin
Fix for issue
No signature of method: static com.google.common.collect.HashMultimap.create() is applicable for a
rgument types: () values: []
Possible solutions: clear(), grep(), get(java.lang.Object), get(java.lang.Object), isCase(java.lang.
Object), grep(java.lang.Object)

Soln: Got rid of googles HashMultimap and replaced with normal Map<?,Collection<?>> implementation
