At two stages, we have intermediate/auxiliary files (the hidden file currently being created by
generator.c and the hidden file used to determine if the rcp command worked properly in
transmit.c). We want to make sure that we do not hash or send or move or delete either file. So
I added a rule not to hash a file starting with a period and not to transmit ".tmpTestSend"
Also, previously the file being created by generator.c was temporarily kept in the working
directory (often my sysnet home directory) and was kept hidden. It's not a good idea
(for performance reasons) to keep this file in the sysnet home folder because that might involve
more transmission of data across the network (to where ever the sysnet home folders are stored).

So I instead stored the currently being generated file hidden in the hash input folder (which
does not process hidden files).
