be read by spambots. email_array is an associative array. Each array corresponds to 1 email address.

To use in html code, as an exampke, add <span class="emailAmyChurckrow">Email Amy</span> where each
email address class starts with email****. This code is different than the email_display_link code
in that any text can be displayed between the <span> tags (e.g. "Email Amy") until the user hovers
over the text, then it will change to the actual email address (e.g. amy@gmail.com).

To add another email address, add to email_array.
