Generate code for this (fragment of a) parse tree

From this tree, assumed to be a syntactically correct action, generate and return the appropriate clojure fragment.

From this tree, assumed to be a syntactically correct condition clause, generate and return the appropriate clojure fragment.

From this tree, assumed to be a syntactically correct conditions clause, generate and return the appropriate clojure fragment.

From this tree, assumed to be a syntactically conjunct correct condition clause, generate and return the appropriate clojure fragment.

From this tree, assumed to be a syntactically correct disjunct condition clause, generate and return the appropriate clojure fragment.

From this tree, assumed to be a syntactically property condition clause where the expression is a a disjunction, generate and return the appropriate clojure fragment. TODO: this is definitely still wrong!

Generate a disjunct value. Essentially what we need here is to generate a flat list of values, since the member has already been taken care of.

TODO: write docs

From this tree, assumed to be one or more syntactically correct actions, generate and return the appropriate clojure fragment.

Generate code for a condition which refers to neighbours.

From this tree, assumed to be a syntactically correct numeric expression, generate and return the appropriate clojure fragment.

From this tree, assumed to be a syntactically correct probable action, generate and return the appropriate clojure fragment.

From this tree, assumed to be a syntactically property condition clause, generate and return the appropriate clojure fragment.

From this tree, assumed to be a syntactically correct qualifier, generate and return the appropriate clojure fragment.

From this tree, assumed to be a syntactically property condition clause for this property where the expression is a numeric range, generate and return the appropriate clojure fragment.

From this tree, assumed to be a syntactically correct rule specification, generate and return the appropriate rule as a function of two arguments.

From this tree, assumed to be a syntactically correct simple action, generate and return the appropriate clojure fragment.

Generate code for a condition which refers to neighbours within a specified distance. NOTE THAT there’s clearly masses of commonality between this and generate-neighbours-condition, and that some refactoring is almost certainly desirable. It may be that it’s better to simplify a NEIGHBOURS-CONDITION into a WITHIN-CONDITION in the simplification stage.
