Title: DATASET (N, transform(COUNT))

First steps to implement an ECL construct. Actually implemented as
NORMALIZE() to avoid shift/reduce conflicts in Yacc/Bison. Node type
enum element added in place of an unused one and implemented in switch/
case blocks as needed (trial and error).

Several corrections by Gavin, now it's producing expected results for
a very limited set of use-cases. Need to trim out the edges, make sure
there isn't a better way of doing each step and create extensive tests,
even if we don't pass all of them as of now. Also needs to transform
back to DATASET().
