<method name="create_code_region">

<description>
Creates a new code region with the selection. At least one single line comment delimiter have to be defined (see [method add_comment_delimiter]).
A code region is a part of code that is highlighted when folded and can help organize your script.
Code region start and end tags can be customized (see [method set_code_region_tags]).
Code regions are delimited using start and end tags (respectively [code]region[/code] and [code]endregion[/code] by default) preceded by one line comment delimiter. (eg. [code]#region[/code] and [code]#endregion[/code])
