 1. Error-checking - invalid regex, Out-of-bounds stuff. Do more testing.
-2. More operators - numeric specifier, escaped characters
+2. More features - Non-greedy operators, backreferences, non-capturing groups, escaped characters inside character classes
 3. Fix adding concatenation operators in shunting-yard function (very janky, compares against operators individually)
 Ideas for flags:
-    -o, -v : Only matched text (separated by newline), Inverted match (just like grep)
-        Also some other grep flags (will have to look into this)
-    NOT IN GREP
-    -s : Substitute (string is provided as argument)
-    -p : Print CSV (or some format) of matches - start idx and end idx
     -m <num> : Print <num>th match (-m 1 = first match, -m 2 = second match)
