4fd86751dc Fix unary operator precedence. 
Before, unary operators that appeared after an operator with higher precedence would be executed after that operator.

However, in evalexpr, the two unary operators are prefix operators negation and not, and prefix operators always happen before operators directly left of them.

532e2ed770 adds iter_(read/write)_variable_identifiers 
seperate iterator returns for read and write variable identifiers.
this is useful in our project and i suspect it might be of use for
others too.

4cc86e7683 Add trait to allow iterating over all variables in a context. 
Both iterating with and without values is supported.
Due to limitations in the language, currently only iterating by cloning is supported. When GATs are stabilised, this should change.

Relates to #108

e70e9d366a Use explicit operator type for reading and writing variables. 
Before, variables written to were represented with the same operator as constants in the AST. This was hacky and confusing to some users.
