BST tests working mostly, added some compilation documentation, and added script to list files that are new to git while ignoring backup files.

+Compile "regular" files with the compile.sh script.
+
+For more complicated setups (like the BST test and implementation), you'll need to initially use gcc -c on each .c source file to get the .o object file thereof.
+Then you have to link them all (in the correct order), with gcc -FLAG1 -FLAG2 -FLAG3...etc FILE1.o FILE2.o...etc -lm
+Then you'll get an a.out executable that runs correctly (make sure you're including the right header files).
