Error highlighting in backend coding environment

In our efforts to make the user experience for test-takers even better we have made big updates to our general-purpose backend coding environment (Codelysis). The code editor now highlights specific lines which have errors and warnings in them. It also provides the exact character location and description of the errors/warnings. This functionality is meant to enhance the coding and debugging experience of test-takers who find it difficult to understand logs and will assist them in understating the issue(s) with their code.
