Detailed Description

template<class Ramp>
class dsp::inertia< Ramp >

Generic inertia using ramping algorithm specified as template argument. The basic idea is producing smooth(ish) output for discrete input, using specified algorithm to go from last output value to input value. It is not the same as classic running average lowpass filter, because ramping time is finite and pre-determined (it calls ramp algorithm's length() function to obtain the expected ramp length)
