Wrote and tested draw tools. I also factored out the elapsed time function
added some dependency information to the makefile
ROI setup and tested
cleaned up the src folder and moved the headers
quick update to gitignore to prevent warnings about not tracking COLA_Test
need to switch off for a bit
all set and tested
updated the time function to seperate "live" time from fixed "frame" time
fixed some warnings
generalized the drawglobalvector to just drawflowpoint
basic tau setup. There are still some calculation issues to resolve, and the sensitivity is way off
