tidy up echo statements

[mvogelgesang]

When reading through create.sh, it gets very busy with color variables wrapping both sides of the text. Instead, create a function which allows the text to be read as the first argument and any wrapping colors and follow on commands at the end.

Use cases

  • echo -e "${oc_COLOR_QUESTION}Describe this goals for this project${oc_COLOR_NOCOLOR}"

• Confirmation message
