+Ret_M Arduino Library
+===========================================
+Small simple library to simplify applying delays utilizing the millis() function.
+Ideal for time sensitive projects, debouncing, or for those who want to avoid utilizing delay(), delayMicroseconds(), or other of the kind that halts the program.
+
+### Usage
+- Include Ret_M.h: #include "Ret_M.h"
+- Initialize a delay: Ret_M name(interval) 
+- name.ret() returns true if the interval has passed.
