"Snap during transform" enabled for fast measurement.
Version history:
v0.7.15 - Measurement of face normals by TNae + extended to cover all cases.
Grouped measured values inside boxes.
v0.7.14
Fixed matrix calculation order.
Replaced region3d_get_2d_coordinates with location_3d_to_region_2d"
from bpy_extras.view3d_utils.
v0.7.13 - Moved property definitions to registration function.
Changed automatic callback adding to manual,
the current API doesn't seem to allow this top be automatically yet.
