	Parses and executes substitute expressions (subexes) So far subex has the following operations: - Concatenation of a and b with ab - Or with \| - Repeat maximally with * - Repeat minimally with - - Copy a specific character 'a' - Copy any character '.' - Store text matching a regex into slot 's': `$s(regex)` - Output text in "" including loading from slots with '$' Regexes support all the same operations as subexes minus storing and outputting This first implementation gives very little thought to efficiency Example: ./main 'according to all known laws of aviation' '$1(.-)$m(( .* )\| ).*"$m$1"' This swaps the first and last words of the input string
