function uiucdownload(varargin)
% UIUCDOWNLOAD Download, extract and clean the UIUC propeller database.
% This function executes the following tasks:
% 1. Download the UIUC Propeller database into database/UIUC-propDB_YYYYMMDD.zip. It also
% saves the file hash into a textfile in oder to prevent useless re-downloads.
% 2. Unzip the database and moves the data files found in volumeX/data/* into
% database/UIUC_propDB/volumeX/*
% 3. The rest of the unzipped files are cleaned up
% 4. The zip file is either kept or removed, based on user input
% -----
%
% Syntax:
% uiucdownload() Download the database (if needed) and its md5 checksum, extract the data
% files and cleanup afterwards.
%
% uiucdownload('force', true) Forces the redownload of the database, even if the md5 checksum
% found locally matches the one present on the UIUC website. Default: false.
%
% uiucdownload('quiet', true) Removes all verbosity from the command line. Default: false.
%
% uiucdownload('removeZip', true) Removes the zipfile as well during cleanup. Default: true.
%
% uiucdownload('removeSum', true) Removes the checksum file as well during cleanup.
% Note that this will result in a forced download of the database if the function is run
% again, even if the zip-file is still present locally. Default: false.
%
% Inputs:
% 'force' : Forces redownload of the database
% 'quiet' : Removes verbosity from the command line
% 'removeZip' : Removes the zip-file at cleanup
% 'removeSum' : Removes the checksum at cleanup. This will force a redownload if the function
% is run again
%
% Outputs:
% UIUC-propDB : Directory containing the all useful data from the UIUC propeller database.
%
% Examples:
% uiucdownload()
% uiucdownload('force', true)
% uiucdownload('removeZip', false, 'force', true)
