SHA3 function is not the NIST SHA3-512

[vith]

The expected SHA3-512 hash of empty string via http://csrc.nist.gov/groups/ST/toolkit/documents/Examples/SHA3-512_Msg0.pdf

A6 9F 73 CC A2 3A 9A C5 C8 B5 67 DC 18 5A 75 6E
97 C9 82 16 4F E2 58 59 E0 D1 DC C1 47 5C 80 A6
15 B2 12 3A F1 F5 F9 4C 11 E3 E9 40 2C 3A C5 58 
F5 00 19 9D 95 B6 D3 E3 01 75 85 86 28 1D CD 26

does not match what this library produces:

> require('crypto-js').SHA3('').toString()
'0eab42de4c3ceb9235fc91acffe746b29c29a8c366b7c60e4e67c466f36a4304c00fa9caf9d87976ba469bcbe06713b435f091ef2769fb160cdab33d3670680e'

Because it's actually keccak-512:

> require('js-sha3').keccak_512('')
'0eab42de4c3ceb9235fc91acffe746b29c29a8c366b7c60e4e67c466f36a4304c00fa9caf9d87976ba469bcbe06713b435f091ef2769fb160cdab33d3670680e'
> require('js-sha3').sha3_512('')
'a69f73cca23a9ac5c8b567dc185a756e97c982164fe25859e0d1dcc1475c80a615b2123af1f5f94c11e3e9402c3ac558f500199d95b6d3e301758586281dcd26'

Any plans on adding a SHA3-512 function that conforms to the specs of sha3 fips 202 ?
