1) remove wildcard imports and use explicit imports 2) refactor to use shared variables from Common/DataType 3) rename to not shadow imports 4) don't assign a variable in a loop (just do final assignment) 5) remove spaces, parens, unused or commented out code, etc. 6) merge unnecessary parent classes into child 7) refactor to share DXE and PEI apriori GUIDs from one place this includes changes to Build and EOT files 8) for PEP8, dont use __ for custom methods.
