at present there's no clear way to get a mapper class from outside of the 
swift build installed into the runtime such that it can be used by 
swiftscript programs - you need to add a registration line somewhere in 
code that gets run during swift startup (as happens for all existing 
mappers in MapperFactory.java) so that references to a mapper in a 
SwiftScript program will end up using the appropriate class.

i would like ultimately to have a way to make that happen without a 
rebuild of Swift.

There are various ways to do it - eg config files listing the bindings 
instead of hardcoding them; or listing classes that are to be loaded (and 
have static initialisers run) at startup time, with the static init code 
knowing the binding.
