patrick 5621820fe4 Added normalization tests for negations. 
These tests ensure that multiple negations are eliminated, negated
quantifiers are replaced appropriately, negations introduced by
reduction are correctly handled, and negated disjunctions and
conjunctions are replaced according to De Morgan’s rules.

patrick 9e9040cac0 Added normalization tests for “forall” statements. 
These tests ensure that universal quantifiers are correctly reduced to
negated existential quantifiers over the negated argument via derived
predicates in preconditions (nested and not) and goal descriptions.

patrick 0cf84dd5ca Added normalization tests for implications. 
These tests ensure that implications are correctly reduced to
disjunctions in preconditions (nested and not) and goal descriptions.

patrick b063f5047e Added basic normalization tests. 
These tests make sure that simple PDDL descriptions are preserved by
normalization.

patrick 08a2eebe2c Removed obsolete test file. 
This file will soon be replaced by a dedicated test suite in the pddl
library and is obsolete thus.

patrick 010e7bf41e Requiring goal to contain only one statement. 
Previously, the parser read the first statement of the goal as its
precondition, but didn’t check that it was properly terminated with a
closing parenthesis. This allowed arbitrary text to be included within
the goal description without error, which was incorrect.

This commit fixes this issue and adds a corresponding unit test.

patrick ca7ae883ee Removed Boost dependency in unit tests. 
Some of the unit tests depended on Boost’s null_sink to redirect the
unwanted test output to /dev/null. This commit adds a simple
NullOutputStream as a replacement and removes the obsolete Boost
includes.

patrick 72fc7493b2 Removed Boost dependency in language distinction. 
As Boost isn’t used in the rest of this project anymore, this commit
removes the unnecessary dependency to boost::bimap just for language
detection, and replaces it with a simple std::map instead.
