Windows testing (AppVeyor)

[Tomnl]

At the moment have any continous integration / testing for Windows.

I will setup up a Windows (AppVeyor) continuous testing. Will do the work on the branch 'appveyor' and then merge when it seems to be working

[Tomnl]

AppVeyor has now been setup. Few points to note though

• The module six needs to be installed prior (this is a known issue in pronto, that Martin is currently looking into again)
• Still getting a failure when I run the mzml2isa script, see appveyor output. Seems to be a problem with the multiprocessing module used in pronto. These 'freeze_support()' errors usually come from when the multiprocessing is made into a binary (link). Although I am not sure if it applies to the .whl file as well.

I have updated the the parsing.py file so that any code that either uses directly or depends on the multiprocessing module is called after:

if __name__ == '__main__':
    freeze_support()

This means that that I had to remove the global variables (e.g. _ONTOLOGIES) to variables.

Using option '-j' for multiprocessing at the file level.

The pronto.Ontology object was only working correctly when I created the object inside the _multiparse function. I am not sure how this will effect speed but I could not get to work using any other approach. Any other suggestions or solutions would be welcome

Six module

Still having to install the six module piror to mzml2isa installation
