- clean up externals
  - What's there for convenience?
  - What's there because it's patched/
- compile on Linux, Mac OS X, Windows
- unit tests for all functions
- standardize name of library "libigl", purge IGL LIB, igl_lib, igl lib, IGL
    Library, etc.
- clean up examples
- standardize use of string/char *, add to style conventions
- standardize Eigen Templates, add to style conventions
+ standardize headers-only vs. static library
- clean up tga.h
+ standardize igl includes #include "cotangent.h" or #include <cotangent.h>
- implement an IGL_NO_OPENGL and IGL_NO_GLUT compiler option
- clean up edgetopology.h
+ clean up mvc.h
- clean up orth.h
- clean up and rename pos.h
- fix bugs in examples/Core/example2.cpp
- replace generic names read.h/write.h with something like read_poly_mesh.h
- replace DynamicSparseMatrix: coeffRef += ---> setFromTriplets()
- create libigltga extra
- rename moveFV.h
- is_border_vertex.h should not require V
- consistent checks/asserts for: manifoldness, closedness, triangles-only
    e.g. check_mesh(V,F,MANIFOLD | CLOSED | TRIANGLES_ONLY)
- clean up Timer.h
- svd.* depends on lapack, should use eigen...
- use preprocessor macros to automatically include .cpp files at end of .h
- unify include opengl with convenience includes
- MatrixBase --> PlainObjectBase
- min_quad_with_fixed should probably be a class
- everywhere appropriate change:
  `#pragma omp parallel for` to `#pragma omp parallel for if (n>10000)` where
  `n` and `1000` are replaced accordingly
