offsetRecon: Reconstructs a response based on input tranfser functions
In driegert/transfer: Frequency Domain Transfer Function Estimation Tools

Based on multiple inputs and offset frequency coherence relationships

1	offsetRecon(H, newData, hTrim = 5, sides = 2, realPart = TRUE)

`H`	A `transfer` object as returned by tf().
`newData`	A `data.frame` containing the columns with the same name as those of `H`.
`hTrim`	An `integer` indicating how points to keep on either side of the center (0 lag) point.
`sides`	A value of 1 (causal) or 2 (non-causal)
`realPart`	A `logical` indicating if the real part of the impulse response should be returned (should be TRUE for real-valued time series).
