+    *  The getValidator() method will take an array of fields from the request body, iterates through them,
+    *  and dynamically adds validation rules for them. Depending on parameters, it may or may not generate
+    *  a form structure for rendering purposes.
+    *
+    *  This method is mostly meant by internal use by means of static proxies (Facades), in order to reduce code repetition;
+    *  Using it outside it's directed scope may cause unexpected results; For instance, the method expects inputs to be in array format, e.g. myFieldNameID1[],
+    *  myFieldNameID2[], and so on and so forth.
+    *
+    *  This isn't checked by the code yet, but if you're implementing it this way in the HTML markup, make sure it's consistent (e.g. use a loop).
+    *
+    *  P.S This method automatically ignores the CSRF token for validation.
