Code Issues Packages Projects Releases Wiki Activity

1) Add in SharingStringPack to make UpdateString only create/update string token in the String Packages that shares String Package with each other. For a String Token to be updated in a Package, TagGUID must be the same and SharingStringPack need to be true too. 

If a package list has both String Package and Form Package registered, the Create/Update of String Token will only be done in this Package List.
2) Add in Doxygen Function headers.
