AMT_CONFIGURATION
Get and set the configuration of the current AMT session

Program code:

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.
