Software Cost Calculator

#======================================================================
#Program: Software Cost Calculation
#Author: William
#Date: 4.18.15
#Dev Env: Python
#Description: This program asks user for the total package units being purchased to then determine what(if any)
#discount bracket the purchase qualifies for. Following showing the discount the total cost after discount should be shown.
#======================================================================

#///////ALGORITHIM START/////
#1 get input from user in form of number of total packages being purchased
#2 perform decision module to find amount of discount
#3 Discount Options
#10-19 = discount 20%
#20-49 = discount 30%
#50-99 = discount 40%
#100 = discount 50%
#4 Display amount of discount (if there is one) 
#5 display total amount of purchase after the discount
#///////ALGORITHIM END/////
