Critically_damped: Critically damped filter
In Kneerav/biomechanics: A bunch of functions useful in biomechanical analysis

This function allows you to low-pass filter data via a critically damped filter

1 2	Critically_damped(raw_data, sampling_frequency = 1000, cutoff_frequency = 20, filter_passes = 10)

`raw_data`	vector of raw numeric data to be filtered
`sampling_frequency`	numeric value indicating the sampling frequency fo the data to be filtered. Defaults to 1000.
`cutoff_frequency`	numeric value indicating the cutoff frequency of the low-pass filter. Defaults to 20Hz.
`filter_passes`	numeric value indicating the number of passes to be made by the filter. Defaults to 10.
