MongoDB now works on Windows

Closes #627 

Assuming you've downloaded and installed mongodb here: http://www.mongodb.org/downloads, here's a set of batch commands that will setup a service and start a mongodb server:

```bat
mkdir c:\data\db
mkdir c:\data\log
echo logpath=c:\data\log\mongod.log> "C:\users\%username%\Anaconda3\mongod.cfg"
echo dbpath=c:\data\db>> "C:\users\%username%\Anaconda3\mongod.cfg"
sc.exe create MongoDB binPath= "\"C:\users\%username%\Anaconda3\scripts\mongod.exe\" --service --config=\"C:\users\%username%\Anaconda3\mongod.cfg\"" DisplayName= "MongoDB 2.6 Standard" start= "auto"
net start MongoDB
```
