potential issue with yamlizing numpy float64s

[partofthething]

I'm using yamlize to serialize some floats. It works great with normal floats but when I get the floats from numpy.linspace, it crashes with the following traceback:

ruamel.yaml.representer.RepresenterError: cannot represent an object: 0.17 

A workaround is to float(val) each thing going in so they're floats instead of numpy.float64s. But it might be nice to have the library be able to handle numpy float64

yuk. yes, numpy is pretty standard so this should work.

I've pushed a hacky fix to master. can you see if that works

I believe this is fixed in 0.7.0
