 * You are implementing the portion of an online dating site where members display their profiles. Most of the
 * profile content is automatically generated from member data. Part of a profile, however, is furnished directly
 * by the member as free-form text. Weblinks frequently crop up in this text, despite a site policy that forbids
 * advertisement and linking of any kind. Your job is to seek and destroy all weblinks in a given piece of text.
 *
 * For example: "espihttp://www.tv.org.superwww.cali.comaladocious"
 * Returns: "espiOMIT1aladocious"
 *
 * Assume the prefix consists of one of the three following strings: http://, http://www., www.
 * And the suffix is one of the five following strings: .com, .org, .edu, .info, .tv
