 * <p><b>Description:</b> <br>validateForm(fieldID, [fieldName], testType)</p>
 * <p>Function used to check (validate) input fields in a form.
 * Can check a single and multiple form input fields, if required.
 * </p>
 * <p>Check single field the information specified in the arguments list is required.<br>
 * Check multiple fields: for each field same information (fieldID, [fieldName], testType) is required.<br>
 * For each following field the input information is same as for the first field (fieldID, [fieldName], testType) separated with comma.<br><br>
 * <b>For example:</b> function call: validateForm(fieldID1, [fieldName1], testType1, fieldID2, [fieldName2], testType2,..etc)
 * </p>
 * <p>
 * <b>Input Arguments:</b>
 * <ul>
 * <li><b>fieldID</b> - the ID of the field to be checked.</li>
 * <li><b>fieldName</b> - "optional". If specified, this name will be used in the "error" message.</li>
 * <li>
 * <b>testType</b> - the test that needs to be done with the required field.
 * </li>
 * </ul>
 * </p>
 * <p>
*  <b>Available testTypes:</b>
*  <ol>
* 	<li><b>R</b>: used to check that a field "REQUIRED" input, select or other input field is entered,selected etc.<br>Can be used with any other testType listed bellow. </li>
* 	<li><b>isEmail</b> : used to check if entered email is in correct form: "username@domain.com".<br>
* if used in the form: "<b>RisEmail</b>" - will mark that the email field is REQUIRED and check if it is valid.</li>
* 	<li><b>isNum</b> : used to check if an input is a number.<br>
* if used in the form: "<b>RisNum</b>" - will mark the field as REQUIRED and check if it is a NUMBER</li>
* 	<li><b>inRange</b>min<b>:</b>max : used to check if the input is a NUMBER and in between the specified RANGE: min:max.<br>
* Extends the testType: "isNum".<br>
* if used in the form: "<b>RinRange</b>" - will mark the field as REQUIRED and do the checkings stated above.</li>
* 	<li><b>isChecked</b> : used to check if a <b>checkbox</b> or <b>radiobutton</b> is checked.<br>
* if used in the form: "<b>RisChecked</b>" - will mark the field (checkbox/radiobutton) as REQUIRED and check whethther it was selected.</li>
*  </ol>
*  </p> 
 * <p>
 * <b>Return</b><br>
 * <b>inputsOK</b> - "true" if the inputs are valid and "false" otherwise.
