are saved & loaded in the .db file, with an API for access at runtime and
the ability to associate a void* pointer with each at runtime.
Also added a capability to dbToRecordTypeH allowing a record type's .dbd
file to add lines to the generated .h file. The C code should be placed
inside the recordtype's braces {} and each line must start with a '%'.
This facility is not currently accessible through a dbStaticLib API.
