RunExpr will evaluate and return the value of a single expression.
RunCode will evaluate a full function body.
RunScript will compile a complete standalone script and return the
return value of its Main() function.
Min/Max with array parameter will return the smallest/largest value of
all elements of the array. If any array element is not an integer, nor
convertible to integer, the function will fail.
I'm not a huge fan of testing for warnings by hijacking the logging
routines, but right now there's no way to exfiltrate warnings from Aul
any other way, so it'll have to do.
Overriding the logging functions from C4SimpleLog.cpp has the nice
additional advantage that expected runtime errors no longer get written
to stdout - this is okay because we're already checking that an
exception is thrown.
