mmspa-v2.1.0

This version is NOT compatible with the clients using mmspa v1.x although... I know that pymmrouting is the only client in the world..

mmspa-2.0.1

1. Simplified function parameters
2. Removed useless exitPostgreNicely function because it can be done nicely without it

mmspa2

1. Improve the performance especially when mmspa works as a service by optimizing IO and caching
2. Fix bugs of memory usage
3. Introduce a new set of public APIs
4. Being compatible with v1.x (for the moment)

Refactored version of multimodal shortest path algorithms library

• Refactored most of the original v1.0 codes
• fixed the bug with multimodal cases in v1.1
• fooltest status: passed
• pymmrouting rundemo test status: passed
• pymmrouting nosetests status: passed

Refactored version of the original mmspa lib

• Files, functions, variables, etc. almost everything in the original implementation has been refactored. But the public interfaces are not changed. So the upper-level libs like pymmrouting will not be affected for the moment.
• Prepare for the 2.0 development work, which is trying to significantly improve the path finding speed
• BUGGY with multimodal case
