Detailed Description

Tapers the N-dimentional ArrayND with a windowFunction.

Usage is straightforward- construct and use. If apply()'s second argument is omitted, the result will be placed in the input array. apply() will return false if input-, output- and window-size are not equal. The only requirement on the windowfunction is that it should give full taper at x=+-1 and no taper when x=0. Feel free to implement more functions!!
