There is one rule: no Excel. Every time I use excel, I have to rename the file and they get lost and I can't retrace my steps. Forcing no excel, I can see every step and fix them where I need to. 

First things first: 
	
1. Correlate all the normalized sum scores with biofilm.  
	* I need a table for these that include the information on what scores are included in the composite scores, the media, and the temperature, as well as the correlation metrics. 

	* `additive_correlator.R` Using the `cor.test()` function described by [STHDA](http://www.sthda.com/english/wiki/correlation-test-between-two-variables-in-r)
