> *Description*: Parses the Subject as a delimited line of text and returns just a single field from that delimited text.
> *Subject Type*: String
> *Arguments*:
>  * _index_ : The index of the field to return. A value of 1 will return the first field, a value of 2 will return the second field, and so on.
>  * _delimiter_ : Optional argument that provides the character to use as a field separator. If not specified, a comma will be used. This value must be exactly 1 character.
>  * _quoteChar_ : Optional argument that provides the character that can be used to quote values so that the delimiter can be used within a single field. If not specified, a double-quote (") will be used. This value must be exactly 1 character.
>  * _escapeChar_ : Optional argument that provides the character that can be used to escape the Quote Character or the Delimiter within a field. If not specified, a backslash (\) is used. This value must be exactly 1 character.
>  * _stripChars_ : Optional argument that specifies whether or not quote characters and escape characters should be stripped. For example, if we have a field value "1, 2, 3" and this value is true, we will get the value {{1, 2, 3}}, but if this value is false, we will get the value {{"1, 2, 3"}} with the quotes. The default value is false. This value must be either {{true}}or {{false}}.
