Notes about the template parser:

- assumption: code is large, tables smaller

- how to generate template based stubs:

	make check asn1_compile_FLAGS=--template > log

- pretty much the same as the generate code, except uses tables instead of code

TODO:
	- Make hdb work

	- Fuzzing tests

	- Performance testing

	- ASN1_MALLOC_ENCODE() as a function, replaces encode_ and length_

	- Fix SIZE constraits

	- Compact types that only contain on entry to not having a header.


SIZE - Futher down is later generations of the template parser
