CPPClassType cannot be cast to ICPPConstructor

First of all, not sure if I am setting this up correctly, as there were no instructions really. I created a folder "\home\daniel\workspace\cpp-to-java-source-converter" and put the repository (master branch) there. I then ran "mvn clean package". I found I needed to create a directory called "crap" under the root directory and put an empty file "test-statements.java" there, as this is expected. I changed to the target directory to run:

`D:\home\daniel\workspace\cpp-to-java-source-converter\target>java -cp cpp-to-java-source-converter-0.1-SNAPSHOT.jar;..\lib\* com.github.danfickle.cpptojavasourceconverter.Main`

Secondly, it doesn't seem to work, due to a class cast exception. Here is the output I get:

```

a-source-converter-0.1-SNAPSHOT.jar;..\lib\* com.github.danfickle.cpptojavasourc

```

Reproduce the failure with `mvn clean package` and the `com.github.danfickle.cpptojavasourceconverter.Main` entry point. Inspect `ExpressionEvaluator.java` at `evalExprNew` lines 143 and 162, then compare failures from `tests/test-bitfield.cpp`, `tests/test-operator-overloading.cpp`, and `tests/test-expressions.cpp`. Done means these inputs no longer produce the reported `ClassCastException` or repeated expression-type failures.
