Added functionality with symbolic functions! Will work towards making a tangent vector now, since derivatives and integrals are possible with symbolic objects.
Added velocity and acceleration information support. Fixed up some minor bugs.
Fixed small bug when a field is constant, rather than a function
Added velocity, acceleration, normal, tangent and binormal vectors. Removed pesky Play button.
Added buttons to enable the motion and unit vectors to display. Removed redundant speed textbox. Need to optimize unit vectors (probably remove the textboxes).

Will begin working on optimizing the graph display.
