Takes three parameters, Location, Mode, TemplateName

Description:

Used to load a template file that contains inner content only into your existing HTML output buffer, which typically is inside a normal complete template.

TemplateName should be in the format of "Module/ThisName" and that will correspond to the file "Templates/Module/ThisName.htm"

Usage:

SubTemplate Location, Mode, TemplateName
SubTemplate Location, ["Append"], TemplateName
SubTemplate ["Runtime"], ["Append"], TemplateName

Cautionary design note: Do not overuse these for small snippets of HTML that are better suited to just live in the MOX code. Save these for mockups only, or larger, static outer structures, that help with layout.
