go_print_utils

very simple wrappers for console output operations

functions:

Print_Lines() -- passed string, returns int

• prints string to console
• returns the number of lines in said string

Clear_Lines() -- passed int, void

• clears int lines from console

Line_Select_MC() -- passed []string, returns string

• assigns letter to each string in slice and prints all strings to console

• prompts user to select a letter

• returns string which corresponds with response letter

• multiple letters can be given as response, separated with spaces

• in this case, function returns all selected strings as a single string separated by commas

• if an invalid option is selected, returns "\a" (bell)

these exist to simplify interactions between a user and command-line application

not all command line applications are complex enough to necessitate a full terminal UI implementation

these should bridge the gap
