ConstructWindow(WindowType, n, winopt)

%   w = window(WindowType, n, winopt)
%
%   an overloaded function of matlab's window function that allows the
%   construction of a window according to a string rather than a function
%   pointer.
%
%   Input Arguments:
%     n: [1x1] window size (in samples)
%     WindowType: [string] type of window. accepted types are:
%        'hamming', 'hanning', 'barthannwin', 'bartlett', 'blackman', 
%        'blackmanharris', 'bohmanwin', 'chebwin', 'flattopwin',
%        'gausswin', 'hann', 'kaiser', 'nuttallwin',
%        'parzenwin', 'rectwin', 'taylorwin', 'triang', 'tukeywin'
%
%   Output Arguments:
%     W: [1xNf] window waveform
