New Features and Improvements

• VarWire process added in lava.proc.io.injector. It works similarly to Injector, but using RefPorts.
• Added watchdog which supports monitoring a port to observe if it is blocked
• GradedVec process enabling graded spike vector layer, which transmits accumulated input as graded spike with no dynamics
• ProdNeuron process, enabling the product of two graded inputs and outputs result as graded spike
• RFZero process, enabling resonate and fire neuron with spike trigger of threshold and 0-phase crossing
• Added BitCheck process, allowing quick check of hardware overflow for bit-accurate process vars
• Added support for multi-instance compilation through compile_option {'folded_view': ['templateName']}

Bug Fixes and Other Changes

• Fixed buffer issue in synaptic delay.
• Added support for numpy array types to use as input weights for Sparse connection process.
