Compile an ERB template file, list of files or a directory.
If a directory is referenced the entire sub-directory structure will be copied to the output directory, compiling any ERB
templates it finds in the process and copying any standard files accross without modification.

ERB is a templating system from Ruby that allows you to embed snippets of Ruby code in any ASCII file to create dynamic
content. Within the context of the origen generator this means that you can include Ruby snippets that reference the target
objects to create dynamic test program sheets, C files, VB files, documentation, etc.

To create an ERB template start with a base ASCII file and append .erb to the end of the file name, upon compilation the
.erb extension will be removed.

There is not much to the syntax, this snippet covers just about everything you need to know:
   %       - A full line of Ruby is prefixed with %, this is removed by compilation
   %#      - A full line Ruby comment, this is removed by compilation
   <%#  %> - An embedded Ruby comment, this is removed by compilation
   <%   %> - An embedded Ruby snippet, this is removed by compilation
   <%=  %> - An embedded Ruby snippet that generates content, the result is output to the compiled file

Full details of ERB syntax can be found here:
   http://www.ruby-doc.org/stdlib/libdoc/erb/rdoc/classes/ERB.html
