/**
    @page prj_tmp Project Templates

    Author: Brian Sidebotham

    Proposal
    --------

    To add new project template functionality to KiCad to facilitate the easy setup of projects
    which have common attributes such as pre-defined board outlines, connector positions,
    schematic elements, design rules, etc.


    Definitions
    -----------

    A template is a directory of files, which includes a directory of metadata. The template system
    name (SYSNAME) is the directory name under which the template files are stored. The metadata
    directory (METADIR) contains pre-defined files which provide information about the template.

    All files and directories in a template are copied to the new project path when a project is
    created using a template, except METADIR.

    All files and directories which start with SYSNAME will have SYSNAME replaced by the new
    project file name, excluding the file extension.


    Metadata
    --------

    A template's METADIR must contain the required files, and might optionally contain any of the
    optional files

        Required Files
        ~~~~~~~~~~~~~~

        /info.html  - Contains html formatted information about the template which is used by the
                      user to determine if the template is what they are after. The &lt;title&gt; tag
                      determines the actual name of the template that is exposed to the user for
                      template selection. Using html to format this document means that images can
                      be in-lined without having to invent a new scheme. Only HTML supported by
                      wxHTML can be used to format this document.

        Optional Files
        ~~~~~~~~~~~~~~

        /icon.png   - A 64 x 64px PNG icon file which is used as a clickable icon in the template
                      selection dialog.


    Operation
    ---------

    The KiCad File menu will be modified to change New from a menu item to a pop-out menu item, in
    the same manor as Open Recent. There will be two options on the pop-out menu:

    Blank -> Will act exactly the same as the current new menu item so that anyone who wishes to
    create a blank project won't have their settings lost or feel alienated.

    From Template -> Will open the template selection dialog.

    The template selection dialog will have a list of icons on the left, and a wxHTML window to the
    right. A single click on a template's icon on the left will load that templates info.html
    metadata file and display it in the wxHTML window.

    A double click on a template's icon will start the new project creation and will open a new
    file dialog. If the user selects a valid location for the new project, the template will be
    copied to the new project location ( excluding METADIR as mentioned earlier ) and any files
    that match the string replacement rules will be renamed to reflect the new project's name.

    The list of available templates will be gathered from the following sources:

    wxStandardPaths::GetExecutableDir()/../share/template/
    wxStandardPaths::GetUserDataDir()/templates/
    wxGetEnv(wxT("KICAD_PTEMPLATES"))
    wxGetEnv(wxT("KICAD"))/template/
