v0.0.3

• ADDED: LweSampleArray.copy() for cloning a ciphertext.

• ADDED: LweSampleArray.roll() that cyclically shifts encrypted bits if a ciphertext.

• ADDED: thread keyword parameter to Context, allowing one to use an existing Reikna Thread object to create a context.

• ADDED: concatenate() for LweSampleArray objects.

• ADDED: __setitem__() functionality for LweSampleArray objects (the source must be another LweSampleArray).

• ADDED: NTT transform now uses Montgomery multiplication for the cases where one of the factors can be prepared in advance, increasing performance (mostly for the multi-kernel bootstrap).

• FIXED: result shape derivation in gate methods of VirtualMachine, including vm.gate_constant() not accepting lists as arguments.
