Progress on the spreadsheet refactor

Progress has been going well. Many of the bugs that were plaguing the program have been removed and overall the spreadsheet looks nicer. The whole thing is still a bit gray but that is ok for now. Not all of the features have be re-implemented but the ones that have are done much better then last time. The spreadsheed has been tested with 5,000,000 datapoints (five million) and it was able to render at a fast enough speed to consider easily usable. the problem will be when those datapoints are all functions and twice the amount of data will need to be stored or more processor time will be used. Ill write more about it later but for now I will leave you with a screen shot!
