function [flags,kv]=amt_configuration(varargin)
%AMT_CONFIGURATION Get and set the configuration of the current AMT session
%
% Usage:
% [flags, kv] = amt_configuration;
% [flags, kv] = amt_configuration('cacheURL', cU);
% [flags, kv] = amt_configuration('silent');
% [flags, kv] = amt_configuration('silent', 'normal');
%
% AMT_CONFIGURATION accepts the following optional parameters:
%
% 'cacheURL',cU Set the download URL of the cache
%
% 'auxdatapath',aP Set the path where the auxdata is stored
%
% 'auxdataURL',aU Set the download URL for the auxdata
%
%
% AMT_CONFIGURATION accepts the following flags:
%
% 'cacheMode' sets the global cache mode, supported options
%
% - global
% - normal
% - cached
% - redo
%
% 'disp' sets the global display mode, supported options
%
% - verbose
% - documentation
% - silent
%
% AMT_CONFIGURATION can be used to retrieve and set the above
% parameters. Any parameter set in the functions amt_auxdatapath,
% amt_auxdataurl, and amt_cache will also be set in amt_configuration and
% vice-versa.
