I was encountering a missing symbol error after building the python bindings

>>> import pyigl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: dlopen(/Users/lawson/Workspace/libigl/python/pyigl.so, 2): Symbol not found: __ZN3igl42internal_angles_using_squared_edge_lengthsIN5Eigen6MatrixIdLin1ELin1ELi0ELin1ELin1EEES3_EEvRKNS1_10MatrixBaseIT_EERNS1_15PlainObjectBaseIT0_EE
  Referenced from: /Users/lawson/Workspace/libigl/python/pyigl.so
  Expected in: flat namespace
 in /Users/lawson/Workspace/libigl/python/pyigl.so

Adding template instantiation to fix it.
