Compiling on 32 bit Linux in debug mode

• Eigen will throw an error about some fixed size matrix not being aligned. This is out of our control
• There is a hacky fix, which involves disabling fixed size vector/matrix vectorization.
• Add this to your CMakeLists.txt

  # Disable vectorization on 32 bit DEBUG mode. Doesn't work yet. Eigen problem
  #NOTE : Checks for 32 vs. 64 bit machine.
