HSTemplate implements a template engine with
output caching support. It can assign template
files a name so that they can be referenced by
that name. The class loads template files from a
given directory, which are HTML files with
embedded PHP code. It can assign variables to each
template that are stored as class variables. The
templates are processed by turning template
variables into local variables and then including
the template file scripts. The results of
processed templates can be cached to avoid
subsequent template processing overhead.
