Fix for regenerate call in ReferencePoint Point property, should be called in unit test directly
Revit 2016 support in installer
Fixed test case failure because of wrong dyn version.

- Replaced old dyn by creating new in 0.6.3. Original dyn file was having error and was not able to open in 0.6.3 and in 0.7.1 it was throwing dummy node error.
- New dyn correctly opening in 0.6.3 and getting migrated to 0.7.1 without having any dummy node.
- Test case is no passing but it will still need more verification, which I will be adding while revisiting test cases.
Updated dyn to have 0.6.3 version instead of 0.7.0 version
Moved regen call to immediately after invoking Ref Point constructor using Face-based Reference
Remove unnecessary references in ReferencePoint tests
Associate node Height property with node border height.
Change distribution logic.

Distribute with even spacing if there is enough space.
Stack elements side-by-side or vertically if there is not.
