Added and tested first example from lesson 1
Removed unneeded data files
Final(?) state of review.pl
Added package.pl with later changes
Added local.pl and watched in fascination as cleaning up the example code automatically prevented the very issue the code was trying to demonstrate.  Don't use $_ outside of one-liners!  Also, it's not a bad idea to spell foreach as "foreach" instead of "for".
Added pieces for demonstrating package-y stuffs
Added require.pl with a simple calendar app (broken)
"Fixed" year and month calculations.
Added changes through the end of lesson 1
Added code for quiz #1
Added package_homework.pl
Refactored date_string functionality to a new subroutine
Moved date_string() to date_lib.pl
Added another.pl to demonstrate code reuse
Added comment about @INC
Added begintest.pl with a glowing testimonial
Added BEGIN blocks
Added forward.pl with known broken date_string call
Added BEGIN around require statement
Finally demonstrating use with barewords
