Fix for libiomp5md.dll Crash Issue

[cmdty]

As highlighted in issue 13 , multiple loading of libiomp5md.dll can cause the Python interpreter to crash. The workaround suggested in the same issue, being added to the Cmdty.Storage documentation, has been seen to fix this but according to the error message printed when the crash occurs, this workaround is 'unsafe, unsupported, undocumented' and 'may cause crashes or silently produce incorrect results'. As such a proper long-term solution should be devised.
