  - AngleUnit, Angle, and CelestialCoord
  - BaseDeviate and child classes
  - BaseNoise and child classes
- Added implementation of fundamental operations:
  - drawImage
  - drawReal
  - drawFFT
  - drawKImage
  - makePhot
  - drawPhot
- Added implementation of simple light profiles:
  - Gaussian, Exponential, Pixel, Box, Moffat, Spergel, DeltaFunction
- Added implementation of simple WCS:
  - PixelScale, OffsetWCS, JacobianWCS, AffineTransform, ShearWCS, OffsetShearWCS, GSFitsWCS, FitsWCS, TanWCS
- Added automated suite of tests using the reference GalSim and LSSTDESC-Coord test suites
