    .Synopsis
       Creates a new user in JIRA
    .DESCRIPTION
       This function creates a new user in JIRA. By default, the new user
       will be notified via e-mail.
 
       The new user's password is also randomly generated.
    .EXAMPLE
       New-JiraUser -UserName testUser -EmailAddress testUser@example.com
       This example creates a new JIRA user named testUser, and sends a
       notification e-mail. The user's DisplayName will be set to
       "testUser" since it is not specified.
    .EXAMPLE
       New-JiraUser -UserName testUser2 -EmailAddress testUser2@example.com -DisplayName "Test User 2"
       This example illustrates setting a user's display name during
       user creation.
