/*******************************************************************************
This functions Job is to set the label for a form field.
All nmWeb forms should have labels enclosed in a span tag with an ID
equal to 'lebel_' followed by the corresponding form field / database field name.

For example a label for a field with the name "username" should have an ID of:

'label_username'

All label ID's should be lowercase.

In order to support multi-lingual websites, the span should enclose ONLY
the text of the field itself, not any punctuation such as a colon (:).
