Adding SimHash implementation to com.google.common.hash

[Patrick Spiegel]

Hi all,

my team is implementing SimHash in the context of web page deduplication for security scanning and we also saw it used for other cases. Since the algorithm originated and seems to be in use at Google, we were wondering if it would make sense to have an implementation as part of the com.google.common.hash package. As of now, there does not seem to be a standard implementation for Java.

What do you think? Would that be a proper fit?

Cheers,

Patrick
