starts hw3 with minHeap.cpp sample code
renames method to be implemented and adds comments to the beginning of file
hacked a bunch of string width thingies based on level
shifts lowest level by one space to the right, makes it look better
fixes #12 by only showing edges for branches that exist. Also some comments and cleanup
fixes #13 by switching to the new sample code for heap. Really only difference is comments and input from user. Also includes cstdlib so that compiler can use exit()
adds function to return max heap level based on its size
fixes #16 sorta by dynamically changing width based on max number of levels, but ends up with slightly messed-up looking display.
