To include a LassoApp file, the [lassoapp_include] method is used. This method accepts one string parameter, which is the path to the file to include. This path does not need to be altered via the [lassoapp_link] method. However, the path should be a full path to the file and should include the name of the LassoApp which contains the file. Additionally, [lassoapp_link] takes content representations into account. Therefore, if the HTML representation of a file is desired, the file path should include the .html extension.
