Fixing Python 3.5 bug with cyflann.

New num_checks parameter for cyflann, kdtrees.

• changes to setup.py to be compatible with conda packaging

Initial release of megaman, containing scalable algorithms for manifold learning including:

• Locally Linear Embedding
• Local Tangent Space Alignment
• Isomap
• Spectral Embedding

These algorithms use FLANN, PYAMG, LOBPCG, ARPACK, and other fast libraries to power through the computational hurdles of manifold learning algorithms.
