-- @AnalyzeExpense@ synchronously analyzes an input document for
-- financially related relationships between text.
--
-- Information is returned as @ExpenseDocuments@ and seperated as follows:
--
-- -   @LineItemGroups@- A data set containing @LineItems@ which store
--     information about the lines of text, such as an item purchased and
--     its price on a receipt.
--
-- -   @SummaryFields@- Contains all other information a receipt, such as
--     header information or the vendors name.
