0.6.2

Minor Analysis Improvements

• Fixed labels in the API graph pertaining to definitions of subscripts. Previously, these were found by getMember rather than getASubscript.
• Added edges for indices of subscripts to the API graph. Now a subscripted API node will have an edge to the API node for the index expression. So if foo is matched by API node A, then "key" in foo["key"] will be matched by the API node A.getIndex(). This can be used to track the origin of the index.
• Added member predicate getSubscriptAt(API::Node index) to API::Node. Like getASubscript(), this will return an API node that matches a subscript of the node, but here it will be restricted to subscripts where the index matches the index parameter.
• Added convenience predicate getSubscript("key") to obtain a subscript at a specific index, when the index happens to be a statically known string.
