got multiple linear regression in, read to data files, exports data to data files.  Should execute optimally based off of regression info.  Don't have it working 100% modularly, but the multiple regression and file input stuff are somewhat modular?  Would be nicer if the data input/output was more modular.  Could write some methods to get rid of reproduced output/input code, but whatevs.  Will test tomorrow, actually haven't tested this yet
