Download Multiple Files at the Same Time Using Start-ThreadJob

##
# Download multiple files at the same time using the Start-ThreadJob cmdlet
#
# The Invoke-WebRequest cmdlet can only download one file at a time. The
# following example uses Start-ThreadJob to create multiple thread jobs to
# download multiple files at the same time.
#
# Start-ThreadJob creates background jobs similar to the Start-Job cmdlet. The
# main difference is that the jobs which are created run in separate threads
# within the local process. By default, the jobs use the current working
# directory of the caller that started the job.
#
# The cmdlet also supports a ThrottleLimit parameter to limit the number of jobs
# running at one time. As more jobs are started, they are queued and wait until
# the current number of jobs drops below the throttle limit.
