Some copy constructors aren't declared in SWIG

[jmarrec]

Issue overview

@shorowit reported this change of behavior between 3.6.1 and 3.7.0-alpha. This used to work in 3.6.1, and now the copy constructor isn't swigg'ed.

[6] 3_7_0(main)> OpenStudio::Point3d.new(OpenStudio::Point3d.new(0, 0, 0))
ArgumentError: Wrong arguments for overloaded method 'Point3d.new'.
Possible C/C++ prototypes are:
    Point3d.new()
    Point3d.new(double x, double y, double z)

from (pry):6:in `initialize'
[7] 3_7_0(main)> OpenStudio::Vector3d.new(OpenStudio::Vector3d.new(0, 0, 0))
ArgumentError: Wrong arguments for overloaded method 'Vector3d.new'.
Possible C/C++ prototypes are:
    Vector3d.new()
    Vector3d.new(double x, double y, double z)

Possible Solution

This is due to this commit of mine, where I applied Rule of 1 in the C++ code, not realizing that this had an impact on SWIG: 565bea0#diff-9ef35a3df57f646ab394775dab1b9d3212fd52c1d5bbce281c2585c6df05a952

For these geometry classes, it's probably a good idea to ensure that the copy ctor is swigged.
