mnu_subsystem(build) - Build Directory

The purpose of this function is to build the file system directory structure which will be used to hold all the files for the subsystem. This will be achieved by creating a directory with the specified name, then copying the contents of the default directory. Not all files may be copied across - those to be excluded are identified in file default/exclude-from-build.txt.

As well as creating the directory structure this function will also perform the following:

• Create a task of type MENU which has the same identity as the subsystem identity.
• Add this menu as an option on the main system menu, which is called main_menu.

This form is accessed by selecting entries in the List Subsystem screen before pressing the 'BUILD DIRECTORY' button in the navigation bar.
