By default, <b>template</b> places the values from your data in the local scope
via the <tt>with</tt> statement. However, you can specify a single variable name
with the <b>varname</b> setting.

_.templateSettings.varname = 'data';

<b>template</b> provides the <b>source</b> property on the compiled template
<b>template</b> provides the <b>compiled</b> property on the compiled template
function for easy precompilation.
