Starting lab 9 vector processing
Incomplete vector processing lab
Should be working upto and include the sort function.
Everything unto and including rotate should be working
Everything unto the sequence function should work, the sequence function is also mostly working.  However, it breaks if a number in the sequence is duplicated out of sequence before the subsequence (ex. list1 { 3, 5, 7, 8, 9, 0, 1, -5, 6, 7, 8, 26 }, list2 { 3, 7, 0, 1, 8 }; is a subsequence of list1, but the duplicate 7 and 8 both through it off).
May possible have the substring thing sorted out, the is the code before first submission.
Correcting issue with empty vectors that was discovered in first submission (everything except for rotate seems to be working now).
Everything should be working now, preparing for 2nd submission
Rotate function still not working, one submission left
Code before third submission
Modified maximum function so that it does not test for empty vectors (the code will crash on an empty vector, beware) because they are not being tested (reporting -1 may lead to a false assumption that the vector has a maximum value of -1 when it is really empty).  This is still before the third submission
Finished lab 9 (strangely, the easier prefix function was broken (one issue was comparing file vector 1 to vector 2 instead of vector 2 to vector 1 or something like that (and some other thing in prefix, may check it later)).  Adding Lab 10, just starting it.
Cleaning up past commits (lab 9 still has a broken prefix function, everything else works) and add lab 10.
