dlib 0.4.0

• dlib.filesystem
  • Platform-specific modules are now grouped by corresponding packages (dlib.filesystem.windows, dlib.filesystem.posix)
  • findFiles is now a free function and can be used with any ReadOnlyFileSystem
• dlib.math
  • Implemented LU decomposition for matrices (dlib.math.decomposition)
  • dlib.math.linear is now dlib.math.linsolve. Added solveLU, a new LU-based direct solver
  • Matrix inversion now uses LU decomposition by default (4x performance boost compared to old analytic method). 4x4 affine matrices use an optimized inversion, which is about 6 times faster
  • dlib.math.utils now uses clamp from latest Phobos if available
  • Removed deprecated functionality
• dlib.core:
  • Moved container modules (bst, linkedlist, etc) from dlib.core to separate package dlib.container. Removed useless dlib.core.method
• Overall: improved compatibility with DMD 2.067.
