Databaker: load xlsx files + cell properties #14
Description
At the moment databaker cannot read xlsx files and store cell properties because of an update to one of its dependancies - xlrd.
- UML breakdown to visualise the relationship between xlrd, messytables and databaker
- Sketch explicit BDD tests to determine file type (xlsx focused) and cell property functionality in databaker
- Complete code to achieve xlsx functionality - reading files + cell properties without the xlrd dependancy.
- [ ] Catch exception raised by dodgy xlsx files - convert into xls and continue with that table loader
- [ ] Change fixture file in main test suite so that duplicate testing for xlsx doesn't get caught by above
- [ ] Implement last cell property functions for xlsx to match xls (any_borders,all_borders,richtext,is_date)
