The function moves files received from the standard submission's form through
file input element(s).
Websubmit_engine built the following file organization in the directory curdir/files
curdir/files

_______________________________________________________________________________

./file input 1 element's name ./file input 2 element's name ....

test1.pdf test2.pdf
There is only one instance of all possible extension(pdf, gz...) in each part
otherwise we may encount problems when renaming files.
+parameters['rename']: if given, all the files in curdir/files are renamed.
parameters['rename'] is of the form: <PA>elemfilename[re]</PA>* where re is
an regexp to select(using re.sub) what part of the elem file has
to be selected.e.g <PA>file:TEST_FILE_RN</PA>
+parameters['documenttype']: if given, other formats are created.
It has 2 possible values: - if "picture" icon in gif format is created
- if "fulltext" ps, gz .... formats are created
+parameters['paths_and_suffixes']: directories to look into and corresponding
suffix to add to every file inside. It must have the same structure as a
python dictionnary of the following form
{'FrenchAbstract':'french', 'EnglishAbstract':''}
The keys are the file input element name from the form <=> directories in curdir/files
The values associated are the suffixes which will be added to all the files
in e.g. curdir/files/FrenchAbstract
+parameters['iconsize'] need only if "icon" is selected in parameters['documenttype']
