1.0-alpha2-118: 1) Delete the old configure.py 2) Delete py_crontab.py bacause we dont use python-crontab anymore. 3) Create function "getUserInputSchedule" and "generateCmd4Crontab" in module "arrangeSchedule". 4) Force the "imme_or_schedu" index to be "1" even if user chose scheduled backup, there must be at least one immediate backup to deal with the pre-existing files. 5) Add function "getUserInputSched" and "generateCmd4Crontab" to "main.py" to deal with scheduled backup and it works fine. 6) Sample.sh is sample file for schedule manager.
