ifndef update and zeroTransformationTest fix

[mbahgatTech]

Fixed the uninitialized array of points in zeroTransformationTest.
Fixed a loop error that went over 4 vectors no matter the numOfPoints value.
Changed the ifndef define names to SCALINGINX

• The test functions are still seg-faulting. They're trying to grab points using getPoint() but there are no points in the list. It might be a better idea to manually create test points and check if your scaling function works on them, that way its independent of the amount of points in the global list
• I'd recommend using CTRL+F and changing all instance of "vector" and "Vector" to "point" and "Point". Just so it stays consistent with the naming conventions.
• I had commented out runScalingInXTests() inside of main.c a bit ago so the seg-fault wouldn't interfere with other groups code, please uncomment it before testing if you're not already :)

changes have resolved issues in tests and should be good to merge
