Add examples for expressing licensing scenarios

[swinslow]

Migrating from @jlovejoy's PR in spdx/license-list-XML#1102, content from that PR below.

To be discussed further, just placing here to move out of license-list-XML

This is a working document to capture licensing examples found "in the wild" and how they would be mapped using the SPDX specification license fields

NOTE TO REMOVE: This is not where this information should ultimately be located, but just putting it here to get it written and can move as appropriate later!!

1. Github example

scenario:

• you have a package with 10 files
• 1 of these files = LICENSE.txt file with a copy of the MIT license
• the other 9 files have no licensing information whatsoever

license info:

at package level:

• Declared Licensem= MIT
• Concluded License = MIT
• Comments on License
• • The package level license is MIT and no other license information is found.

at file level:

• Declared License
• • LICENSE.txt file = MIT
• • other 9 files = NONE
• Concluded License
• • LICENSE.txt file = MIT
• • other 9 files = MIT
• Comments on License
• • LICENSE.txt file = (no comment necessary)
• • other 9 files = The package level license is MIT and no other license information is found.
