Build a quaternion polynomial guidance profile on a segment.
The polynomial representing the quaternion components are generic polynomial functions.

Real time is used (not reduced time).

Parameters:

q0 - the polynomial function of date representing the q0 quaternion component

q1 - the polynomial function of date representing the q1 quaternion component

q2 - the polynomial function of date representing the q2 quaternion component

q3 - the polynomial function of date representing the q3 quaternion component

timeInterval - the time interval of the guidance profile segment: only used as validity time interval (no impact on orientation value at any date)

needsNormalizationIn - true if the quaternion polynomials need normalization
