Autoregressive (AR) Filter Base Class.

This class implements a autoregressive (AR) filter according to

\[ a(0)*y(n) = x(n) - a(1)*y(n-1) - ... - a(N)*y(n-N) \]

where a is the filter coefficients, x is the input and y is the output.

When filtering a vector, the length of the output vector equals the length of the input vector. Internal states are kept in a filter memory. The first time the filter is used the internal states have been set to zero.

The class is templated as follows:
