Function split_program_name

simcore/framework/src/cli/cli.hpp:3133–3153

Split a string into a program name and command line arguments the string is assumed to contain a file name followed by other arguments the return value contains is a pair with the first argument containing the program name and the second everything else.

/// the return value contains is a pair with the first argument containing the program name and the second
/// everything else.
