  /**
   * Returns a report of the compatibility info map based on the compatibility level. Each line is prefixed with
   * a line type enclosed in []. Supported report line types are:
   * 
   *   [RS-C] - String describing a restspec change that is backward compatible.
   *   [RS-I] - String describing a restspec change that is backward incompatible.
   *   [MD-C] - String describing a model(PDSC) change that is backward compatible.
   *   [MD-C] - String describing a model(PDSC) change that is backward incompatible.
   *   [RS-COMPAT] - Boolean indicating if the full compatibility check was restspec backward compatible for the provided compatibilityLevel
   *   [MD-COMPAT] - Boolean indicating if the full compatibility check was model backward compatible for the provided compatibilityLevel
   * 
   *
   * This report will then be parsed by {@code CompatibilityLogChecker} to provide results to the pegasus gradle plugin.
