Documentation enhancements

[extrapilot]

It would be useful if the help files contained additional information on error conditions. For example, in the MMC library, a function like MMC_WRITE_SECTOR returns "1" if 'there was an error in sending the command,' and "2" if 'there was an error in writing (data rejected)". But it is not clear if error "1" implies the MMC card returned an error, or if the library timed out, etc.

So perhaps my request is to expand the internal (library) diagnostic capability for library error reporting, or maybe it is just expansion on the fault conditions associated with existing error types- probably both.
