Takes one parameter, FieldName
Field should be in the format of
TableName.FieldName#Deff where Deff is one of: Label, Attr, Note, or DevNote
GetFieldDefs is great for HtmlForm, in other cases we need easy access to a given Field's Database definitions in the Top Query without having to always rebuild a wrapper around
GetFieldDefs to do this.
This Top Query Function may also be used as a Function for the Text Work Query Command.
