Windows for Modal Testing

[JakeZw]

I have implemented the windows in Ron Potter's seminal paper "Compilation of Time Window and Line Shapes for Fourier Analysis", http://papers.vibetech.com/Paper64-CompilationofTimeWindowsandLineShapesRPotter.pdf along with the Force and Exponential Windows found in Fladung, "Application and Correction of the Exponential Window for Frequency Response Functions".

The paper by Potter gives the characteristics and use cases for his windows, which I have summarized. The force and exponential windows are typically used for impact testing for the purpose of experimental modal analysis. I have the zerophase=false form for both cyclical and non-cyclical use cases.

If someone would to implement these windows in DSP.jl I will provide them my code as a basis. Just curious what the interest is.
