function ShadedPlot( meanarray,disparray,array,orientation,varargin)%,orientation,name,color,marker )
%ShadedPlot - Plots the line with shaded region.
%
%   Syntax:
%       ShadedPlot(meanarray,disparray,array,varargin)
%
%   Description:
%       ShadedPlot() - Plots the line with shaded region under the line.
%       Depending on the 'orientation', It is possible to have a vertical
%       (e.g., altitude) or horizontal (e.g., time) representation.
%
%   Inputs:
%       meanarray   - vector for the Line (Average Data)
%       disparray   - vector for the Shaded Region (Dispersion Data)
%       array       - vector for the y-axis (e.g., altitude) or the x-axis (e.g., datetime)
%       orientation - orientation of the plot 'vertical' or 'horizontal'
%       varargin    - Custome parameters such as color,marker, markersize,
%       displaynames, legend location
%
