centrifugeR: Non-trivial balance of centrifuge rotors

Centrifuges are indispensable instruments in biology laboratories. For the safe operation of centrifuges, ensuring balance is a must. Loading test tubes in opposite holes and adding dummy tubes are far from the only ways to balance the centrifuge rotors. The balance can be sought through higher-order symmetrical configurations of tubes, which offer operational advantages, particularly in dealing with tubes of unequal mass. Because these configurations are somewhat complicated, an open-source tool was introduced to assist centrifuge users in the adoption of this non-trivial approach.
