Import CubeMX code into project

#!/bin/sh

#
# This script helps with importing framework source files from an STM32CubeMX
# code generation dump. It does not prepare the complete project, and is
# mainly intended for use in tracking framework code changes.
#
# Files copied by this script may overwrite local changes within the project,
# so changed files should be carefully inspected before checking them in.
#
# This script can also be used as documentation on how the STM32CubeMX code
# dump is translated into the project directory structure.
#

#
# Validate arguments to get input and output paths
