User-defined functions are not supported

[dsyme]

This is documenting a feature request - users of this type provider who need this feature are encouraged to implement it and submit the implementation back to this repo.

Hive supports user-defined functions, normally written in JVM languages.

This type provider could be extended to allow UDFs written either as Java strings or F# source code. If using the latter then an F#-quotation-to-Java-source-text translator would almost certainly be needed, something which would be more generally useful too.
