Mpilot

Breaking Changes
---
* Renamed `MeanToMid` command to `CvtToFuzzyMeanToMid`

closes 4

Improvements
---
* Write tuples one per line when serializing a model to string
* Preserver order of arguments when parsing, or when `Program.add_command` is called with an `OrderedDict`

Build
---
* Update `six` dependency to accept any version. ArcGIS comes pre-installed with an older version of `six`, which cannot be uninstalled by pip. The previous dependency specification was newer than the ArcGIS-installed version, and thus installing `mpilot` would cause an error.

Build
---
* Use the same optional NetCDF version for Python 2 and 3 to avoid a bug in which wheels would install undesired extra dependencies on Python 2

This release only contains changes to the build/publish process.

Improvements
---
* Added support for numpy 1.9.3, which is used by ArcGIS Desktop
