Generate polynomial trajectories using B-splines

`[`

generates a piecewise cubic B-spline trajectory that falls in the control polygon defined by
`q`

. The trajectory is uniformly sampled between the start
and end times given in `tInterval`

. The function returns the positions,
velocities, and accelerations at the input time samples, `tSamples`

. The
function also returns the piecewise polynomial `pp`

form of the
polynomial trajectory with respect to time.
