Editing Template:Park trail table template

<noinclude>This is a format template for the [[Template:Park trail table]]. It is expected to be used in conjunction with a semantic query. The parameter userparam is part of the format 'template' and is used to specify the switch to 'row' when needed. Otherwise repeated calls can use the template to envoke the intro, outro, or a header output. If using the header output, you can specify the additional 'header' parameter to give it the text to place in the header row. 

This template was created to handle the combination of trail pages and trail stubs (park page subobjects). As of now, this seems to be the only way to seamlessly accomplish that in a pleasing format. 

Trail stubs are checked for pages already created with that name. If it is and info-error box is shown explaining the problem. Trail stubs that don't have a page already created (or name collision with an existing page) are given a red link to the [[Form:Trail|Trail Form]] with fields prepopulated based on the trail stub information. 

<p>It expects the following usage format.
<pre>
{{Park trail table template
 |#userparam=
 |header=
 |trail=
 |distance=
 |difficulty=
 |marking=
 |highlight=
 |use=
 |park=
}}
</pre>
But its usage in practice is like this with the middle two calls being used to get the trails specified as pages and the second to get Trail Stubs created on the park page.
<pre>
{{Park trail table template|#userparam=intro}}
{{#ask:[[Category:Trail||Trails]] [[Park::Warriors' Path State Park]]
 |mainlabel=trail
 | ?Trail Distance#mi-p2=distance
 | ?Difficulty=difficulty
 | ?Trail Marking=marking
 | ?Trail Highlight=highlight
 | ?Trail Use=use
 |format=plainlist
 |headers=hide
 |template=Park trail table template
 |userparam=row
 |named args=yes
}}
