Quaternion interpolation between two quaternions

calculates the quaternion interpolation between two normalized quaternions `qi`

=quatinterp(`p`

,`q`

,`f`

,`method`

)`p`

and `q`

by
interval fraction `f`

.

`p`

and `q`

are the two
extremes between which the function calculates the quaternion.

Aerospace Toolbox uses quaternions that are defined using the scalar-first convention.
