/**
 * A simple implementation of the String.equals functionality. It can be used as
 *
 * {@code
 *  {%@equals /something/something%}
 * }
 * 
 * The return value of the macro is either the string literal {@code true} or the string literal {@code false}.
 * 
 * The arguments can be separated by space in case the {@code something} does not contain any space, using any non alpha
 * numeric character or using `regex` as defined in {@link javax0.jamal.tools.InputHandler#getParts(Input) getParts()}
