removed LIMS::Local::ExcelHandler->initialise_fh() step, ->{FILEHANDLE} now generated at object creation in trial_cases.pl & C::DataImport::chimerism_prep()
bugfix LL::ExcelHandler - no access to LIMS::error() method so replaced return with die; removed BEGIN block in sysmex.pl script - generates Carp version error in Deb7 perl version; changed directory permissions on sessions & src/data dirs to allow apache to read/write without requiring 777
added ability to update CfH data files from referral_sources lookup page; changed permission definition required to upload data file from admin to edit_pid
reverted to original Text::CSV::Simple, but added new on_failure trigger with more explicit wanring - in Local::ExcelHandler; lantronix_socket has alter_admin function when data string appears corrupt - not working yet
