Element wildcard (*) is not supported on intermediate elements and produces wrong results on terminal nodes

[eliaslevy]

This works

JsonPath.on({'a'=>{'b'=>{'c'=>1}}}, '$.a.*') # [{"b"=>{"c"=>1}}] 

but note is produces the wrong result. It should generate [{"c"=>1}].

This doesn't work

JsonPath.on({'a'=>{'b'=>{'c'=>1}}}, '$.a.*.c') # []

It should return [1].

Note that http://jsonpath.curiousconcept.com/ produces the expected results in both cases.

Also, this works

JsonPath.on({'a'=>{'b'=>{'c'=>1}}}, "$.a['b'].c") # [1]

but this doesn't

JsonPath.on({'a'=>{'b'=>{'c'=>1}}}, "$.a[*].c") # []

[eliaslevy]

For what its worth, one can emulate the wildcard by doing [?(@)]. E.g.

JsonPath.on({'a'=>{'b'=>{'c'=>1}}}, "$.a[?(@)].c") # [1]

Its an ugly hack, but it works.
