0621 Need simple description of borehole trajectory section

A BOREHOLE TRAJECTORY SECTION has properties of geometry in 1D, 2D and 3D, and a property of LENGTH, but is lacking properties of AZIMUTH and INCLINATION (to go along with LENGTH) that simply describe its orientation and direction.

Add properties of azimuth and inclination.

Properties describing the average inclination and azimuth of a wellbore trajectory section were added.

Added objects:
pty_azimuth.borehole_trajectory_section (Attribute)
pty_inclination_from_vertical.borehole_trajectory_section (Attribute)
borehole_trajectory_section.pty_inclination_from_vertical (Attribute)
borehole_trajectory_section.pty_azimuth (Attribute)
pty_inclination_from_vertical.borehole_trajectory_section (Attribute)
pty_azimuth.borehole_trajectory_section (Attribute)

Modify uniqueness constraint

Modify the uniqueness constraint to add the new relationships.

Modified objects:
pty_azimuth.si (Unique rule)
pty_inclination_from_vertical.si (Unique rule)
