Project 3 Grading Concerns

* warnings
o you may get extra warnings if you redundantly compile files
* we deduct for these
o you may get warnings for extra spaces in your make file
* we don't deduct for this
o you may get warnings for missing flags (-w0 or -std)
* we deduct for these

* sumitted but failed all test
o tar
* be careful when tarring
* 1st time no problem
* after first time if you tar -cvf p4.tar * and your other p4.tar file 
gets included, when we untar it your new tar file gets corrupted
o if you have uninitialized variables
* we deduct minimally for these

* Bst * v = new Bst();
o we will rerun this with
* Bst *v = new Bst('v');
o but you should fix it for P4

* .o files
o -2 points each will be changed to -1 point each
 
* if after you get your graded project back you can change just up to 5 
lines and it works correctly, we will give a 5 point penalty and regrade 
it if you request

* if you clearly made a mistake - left in debug statements, etc. and ask 
for a regrade because your output doesn't diff
o course policy has been either 0 points returned or -5 points deducted
o we are going with -5 points, and regrade (see above)
