bug fix on typo in quotations
needed to add this to be able to use objectify
added objectify to maven dependency
added two new API calls for share folder

shareFolder.add api call added to make an insertion to datastore for sharedFolders list and shareFolderLink reference list.
shareFolder.getSharedFolders retrieves the shared Folders that a company is currently sharing.
added this to GCSFilesResponse to get json array

this could be put in a seperate response file too if needed so it won't be mixed in the the files response.
made share permission class

this class is to contain the share company id and the permissions but in its own class so that the json can group share companies by folder name & originCompanyId.
made ShareFolderLink class

I needed a different data structure and class to insert and keep track of share folder links that is more flat and does not group by folder name.
This way when the client wants to get the folders that are shared from other companies...it can just filter this list by sharedCompanyId and get the folderNames. I added permissions just incase I need it.
made ShareFolder class

This is the class that groups permissions by foldername and originCompanyId.
This is a good data structure that will be serialized to json to send to the client and a good candidate for the shared folders management list where you can do updates on the permissions and companies that folder is shared with.
added ofy Service

this is best practice to get objectify to register your entity classes before you use ofy().
added dataStoreService for CRUD logic

the logic for add shared folder was a bit big and thought it be best to have a service like gcsService that put that code for these CRUD operations and didn't dirty up the StorageAPI code. keep it separated.
added more descriptive comments

and changed some better variable names that make more sense.
removed classes due to refactor
 updated ofyService due to deletions
refactor to return shareFolderLink
folderName needs @index to be filtered
cleaned up spacing and tabs
