Order of operations is not respected

[astromme]

Because of the way the AST compiles down into C code the operator precedence is not honored. The AST gets it right but writes it out wrong for C to interpret. It is going to be more involved than just putting () around every function, that seems to break things. (maybe makes things into bools??)

operations.chestnut

print("4 * (1+1) should equal 8, in reality it is %s", 4 * (1+1));

output:

$ ./operations
4 * (1+1) should equal 8, in reality it is 5

When compiling the AST I now put parentheses around everything, which fixes this issue but makes the generated code look awful. The correct way to fix this is to re-create the parentheses when compiling, which requires the compiler (in addition to the parser) to know about operator precedence.
