  10 Notes about the template parser:
  11
  12 - assumption: code is large, tables smaller
  13
  14 - how to generate template based stubs:
  15
  16         make check asn1_compile_FLAGS=--template > log
  17
  18 - pretty much the same as the generate code, except uses tables instead of code

  20 TODO:
  21         - Make hdb work
  22
  23         - Fuzzing tests
  24
  25         - Performance testing
  26
  27         - ASN1_MALLOC_ENCODE() as a function, replaces encode_ and length_
  28
  29         - Fix SIZE constraits
  30
  31         - Compact types that only contain on entry to not having a header.
  32
  33
  34 SIZE - Futher down is later generations of the template parser
