[~exceptionfactory] Is there documentation and or diagrams on how the 
{code:java}
org.apache.nifi.schema.inference.InferSchemaAccessStrategy
{code}
and its related classes work? I am having a hard time wrapping my head around this in order to integrate this with an Excel reader. I believe I have the basic strategies working but I am looking to see how I can implement the inference and header strategies similar to the CSV reader.

> A new Excel Record Reader should be implemented to support reading XSLX spreadsheet rows as NiFi Records. This Reader will enable integration with various record-oriented components, obviating the need for the narrowly focused ConvertExcelToCSVProcessor. The initial version of the Excel Reader should not support the legacy binary XLS format.
> The ExcelReader should use a library that supports reading from a stream of rows to avoid consuming large amounts of heap memory during processing.
> The ExcelReader should support configurable properties to read selected sheets. With Excel supporting typed field values, some amount of field type mapping will be required. Additional input filtering properties should not be implemented as existing Processors like QueryRecord support a wide variety of filtering and projection use cases.
