Create a custom form and using the details from the form, create a customer record

Overview

For this we use script type as Suitelet, which has entry point – onRequest. First, create a custom form which includes the following details – Name, E-mail, Phone, Sales Rep, Subsidiary (and other fields if required). Now, Create a submit button and on clicking the same, It should display the details entered by the user. And these details should be used to create a customer record. (Also never forget to Include N/ui/serverWidget module in Suitelet.)
