% NAME
% plot_modwt_rcwsvar -- Plot the rotated cumulative sample variance of the MODWT wavelet coefficients.
%
% USAGE
%   [haxes]  = plot_modwt_rcwsvar(rcwsvar, [title_str], [xaxis], [xlabel_str], ...
%                                 [axesProp], [level_range])
%
% INPUTS
%   rcwsvar      = NxJ containing rotated cumulative sample variance of
%                    the MODWT wavelet coefficients
%   title_str    = (optional) character string or cell array of strings containing title of plot.
%   xaxis        = (optional) vector of values to use for plotting x-axis.
%   xlabel_str   = (optional) character string or cell array of strings containing label x-axis.
%   axesProp     = (optional) structure containing axes property values to
%                     override for C subplot.
%   level_range  = (optional) number or range of numbers indicating subset of
%                    levels (j's) to plot.  
%
% OUTPUTS
%   haxes   =  (optional) handle to axes for original data series (C) subplot.
