Progress: controller program, working on execute script logic.

Progress: controller program, working on execute script logic.

I have been tossing around how exactly I want to implement the execute with piped data.
I have decided that I should clean up the parameters and redesign it to accept a few specialized structures.

Before I do that, I wanted to confirm that the pipe to shell (such as bash) works as I expect it to.
This tweaks the code to a temporary state where I can automatically execute some bash script with some string piped to it.
This seems to work as expected and errors out as expected.

I also need to write some asynchronous functions to help with managing asynchronous processes.
This might require a new series of projects (f_asynchronous, fl_asynchronous, etc..).

Note: "bash" was used as the default script, but I really need to provide some sort of configuration to change this.
