Template Parser Directives

The template parser recognizes 3 special keywords (directives):

• $\backslash$include - must be followed by a filename. Forces parser to temporarily stop reading current file and begin reading the include file. Once the parser reaches the end of the include file it continues with the current one. Include files can be nested. HDU definitions can span multiple files.
• $\backslash$group - marks beginning of GROUP definition
• $\backslash$end - marks end of GROUP definition
