Summary: Tolog SELECT clause syntax is wrong

Initial Comment:
The SELECT clause of the tolog 0.1 language is defined
in BNF as:

[19]   	selectpart	   ::=   	'SELECT' selectlist 'FROM'
[20]   	selectlist	   ::=   	selpart (',' selpart)*
[21]   	selpart	   ::=   	variable | aggfun '(' variable ')
[22]   	aggfun	   ::=   	'count'

(ref:
http://www.ontopia.net/topicmaps/materials/tolog-spec.html)

The current tolog engine supports only one count and it
must be preceded by a variable. The tolog
implementation should be updated to match the tolog 0.1
BNF productions.

This will be addressed as part of the tolog 1.0
implementation, so I don't want to fix this for the
soon-to-be-deprecated 0.1 implementation.
