Fix the issues reported by phpcs

Fixing all the php coding standard issues and warnings in this patch. Please Review.

I will review this.

Patch #2 tested and applied successfully, all errors and warnings are fixed now.
Created MR !9 for this issue.
Please review.

Thanks.

 /**
  * @file
- * Describes hooks and plugins provided by the Corresponding entities references module.
+ * Corresponding entities module offers hooks & plugins for references.
  */

The correct short description for those files is Describes hooks provided by the [module name] module.

- *   Differences arrary calculated by CorrespondingReference::calculateDifferences()
+ *   Diff. arrary calculated by CorrespondingReference::calculateDifferences()

The existing description is correct, except for a typo.

function hook_cer_differences_alter(\Drupal\Core\Entity\ContentEntityInterface $entity,
-  array &$differences, $correspondingField) {
+  array &$differences,
+ $correspondingField) {

As per Drupal coding standards, function declarations are written in a single line.

+  /**
+   * Builds the header row for the entity listing.
+   */
   public function buildHeader() {

The return value is not documented.

+  /**
+   * Builds the row for the entity listing.
+   */
   public function buildRow(EntityInterface $entity) {

Parameters and return value descriptions are missing.
