// Data Structure for Generic Tower Crane (?)
// Program finds necessary size of concrete base to be poured and overall weight of tower segment.
// Note since the horizontal jib has not yet been accounted for the math to calculate the base weight is currently arbitrary. Once the moment of the crane is available, trigonometric functions can be used to calculate a more accurate size and weight.
