makeTriangles now works, set up to work with any number of inputs. Next step is to input more data and see if it works.
Added get_AllFiles.m and get_XYHeading.m, as well as some sample alog files that were grepped. AllFiles creates a nav variable that includes data from all given file names. It uses get_XYHeading to dump the info. Works with makeTriangles, but it is very slow, need to find a way to speed it up. Should set it up to create snapshots for a given time period.
