- The logic for switching input-mode was previously completely
encapsulated within the #inputMode directive, but without any
programming equivalent. Furthermore, the encapsulation in inputMode
made the logic less clear in other places.
Exposing the inputMode as an enum with direct access from entry
simplifies things a fair bit.
- eliminate one level of else/if nesting in entryIO.C for clearer logic
- for dictionary function entries, simply use
addNamedToMemberFunctionSelectionTable() and avoid defining a type()
as a static. For most function entries the information is only used
to get a name for the selection table lookup anyhow.
- similar to the #include directive, but does not generate an error if the
file does not exist.
Note: opted for an explicit naming #includeIfPresent rather than #cinclude
