Remove leading underscore variables
 2021-05-18 16:44:54 -07:00
Aaron Fisher e758c37691 Removed nearly all leading underscores for variable names. Every once in a while one of these will confilct with standard libraries in an oddball compiler and it's best to just avoid this problem alltogether. 2021-05-10 16:06:51 -07:00
