def retrieve_files(host, filelist, destdir='.', indicator=None):
"""
<Purpose>
This retrieves files from a host to a destdir.
<Arguments>
host:
'host' holds two things, a server name and target directory.
For example, if you want to retrieve files from '/tmp/' directory
in 'quadrus.cs.arizona.edu' server, the 'host' will be
'quadrus.cs.arizona.edu/tmp'.
filelist:
'filelist' is a list of files which need to be retrieved.
destdir:
'destdir' is a destination directory where retrieved files will
be placed. A user should have 'destdir' exist before retrieving
files. 'destdir' should be a string. Default is a current dir.
indicator:
'indicator' is a module which has set_filename and
download_indicator functions. 'indicator' will be passed in
'urlretrieve' function so that progress bar will be shown
while downloading files. Default is 'None'.
<Exceptions>
None.
<Side Effects>
None.
<Returns>
(True, grabbed_list)
'grabbed_list' is a list of files which are retrieved
