* Template strings look like

* or "%{date}"
*
* This syntax is somewhat similiar to the one found in the Eclipse editor.
*
* There are certain common placeholders (macros), which get assigned a
* default initialValue, If the second parameter does not a given value.
* For all others the initial value is the name of the placeholder.
*
* Placeholder names may only consist of a-zA-Z0-9_
* Common placeholders and values are
*
* - index: "i"
* - loginname: The current users's loginname
* - firstname: The current user's first name retrieved from tdeabc
* - lastname: The current user's last name retrieved from tdeabc
* - fullname: The current user's first and last name retrieved from tdeabc
* - email: The current user's primary email adress retrieved from tdeabc
* - date: current date
* - time: current time
* - year: current year
* - month: current month
* - day: current day
* - hostname: hostname of the computer
* - cursor: at this position the cursor will be after editing of the
* template has finished, this has to be taken care of by the actual
* implementation. The placeholder gets a value of "|" assigned.
*
* If a macro is started with a % (persent sign) like "%{date}" it isn't added
* to the list editable strings ( for example TAB key navigation) if a value
* differing from the macro name is found.
*
* If the editor supports some kind of smart indentation, the inserted code
* should be layouted by the indenter.
