Intention of this info is to be downloaded by MDrivenDesigner at startup to guide what tagged value can be used where.

All valid Tagged values must be added here!!! We deliberately skip the ones that has Designer properties already

#TargetType.TaggedValue	CommaSeparatedExampleValues	ShortDescription
#Column.DataIsImageUrl	True,False	When set on a ViewModelColumn the data string is treated as an Image URL by Turnkey
#Column.DataIsLink	True,False	When set on viewmodelColumn the string data within is treated as a hyperlink
#Column.BlobDownloadLink	True,False	When set on a ViewModelColumn the Blob content can be downloaded by a hyperlink rather than rendered
#Nesting.Editable	True,False	Nesting that represent grid will render web grid cells as possibly editable (depending on read only expression)
#Column.MaxFetch	<int>	Declare "MaxFetch=<int>" on the ViewModelColumn action that initiates the search to change from the default (100)
#Attribute.ExternalBlobStorage	True,False	Large files can be kept out of the granular model database.This is a turnkey functionality only - and the the files will be stored (with simplest outofthebox solution) on disk App_Data/BlobStorage
#Column.StringFormat	<identifier>	WPF Only: TaggedValue StringFormat on ViewModel column has precedence for finding a binding Stringformat - normally the stringFormat is taken from <StyleRef>.StringFormat , but if this TV has value - <value>.StringFormat is used
#Span.MVC	True,False	The Turnkey WebApplication uses MVC for index and login pages - it defaults to angularjs for all other pages. To get MVC on other pages you must set tagged value MVC=true on ViewModel.
