Log Message:
Initial import of HElib, a library to perform homomorphic encryption,
into the Packages Collection.

	HElib is a software library that implements homomorphic encryption
	(HE).  Currently available is an implementation of the
	Brakerski-Gentry-Vaikuntanathan (BGV) scheme, along with many
	optimizations to make homomorphic evaluation run faster, focusing
	mostly on effective use of the Smart-Vercauteren ciphertext packing
	techniques and the Gentry-Halevi-Smart optimizations.
