long types not supported as numeric, attempts to evaluate cell[0] fails
Created originally on Bitbucket by Anonymous
Hi, great library. There is a bug for long types in openpyxl-1.5.2-py2.6.egg/openpyxl/writer/dump_worksheet.py on line 193. Should be:
elif isinstance(cell, (int, float, long)):
Might be other types this fails on then. If the check fails on the type then line 199 throws an exception.
