-
-==== Description
-
-A simple encoder that constructs a table of __Comma-separated values__ (CSV).
-
-Structure:
-
-* Each record represents a row
-** The sequential order of literal _values_ forms a *row*
-** The sequential order of literal _names_ of the first record is used as _header_ (Optional)
-
-CSV Dialect:
-
-* Delimiter: ,
-* Quote Char: "
-* Line Terminator: \n
-* Quoting: Quote All
-
-Example Output:
-
-```
-"output","example","2018"
-```
-
-==== Syntax
-
-```
-encode-csv([separator],[includeHeader],[includeRecordId])
-```
-
-==== Parameters
-
-* `separator`: Delimiter symbol (Default: comma)
-* `includeHeader`: Add a header with column names (Default: false).
-* `includeRecordId`: Add the record id as first element of each row (Default: false).
-
-==== Example
