{{task heading}}
Write a function or program that can split a string at each non-escaped occurrence of a separator character.

It should accept three input parameters:
:::* &nbsp; The <b>string</b>
:::* &nbsp; The <b>separator character</b>
:::* &nbsp; The <b>escape character</b>

<br>
It should output a list of strings.

{{task heading|Details}}

Rules for splitting:
* The fields that were separated by the separators, become the elements of the output list.
* Empty fields should be preserved, even at the start and end.

<br>
Rules for escaping:
* "Escaped" means preceded by an occurrence of the escape character that is not already escaped itself.
* When the escape character precedes a character that has no special meaning, it still counts as an escape (but does not do anything special).
* Each occurrence of the escape character that was used to escape something, should '''not''' become part of the output.


{{task heading|Test case}}
Demonstrate that your function satisfies the following test-case:
{| class="wikitable"
|-
! Input
! Output
|-
| style="vertical-align:top" |
{| style="border-collapse:collapse; border:none" border="0"
|-
| style="border:none; text-align:right" | string:
| style="border:none" | <pre style="display:inline;padding:0.1em;margin:0.3em;">one^|uno||three^^^^|four^^^|^cuatro|</pre>
|-
| style="border:none; text-align:right" | separator character:
| style="border:none" | <pre style="display:inline;padding:0.1em;margin:0.3em;">|</pre>
|-
| style="border:none; text-align:right" | escape character:
| style="border:none" | <pre style="display:inline;padding:0.1em;margin:0.3em;">^</pre>
|}
|
{| style="border-collapse:collapse; border:none" border="0"
|-
| style="border:none" | <pre style="display:inline;padding:0.1em;margin:0.3em;">one|uno</pre>
|-
| style="border:none" | <pre style="display:inline;padding:0.1em;margin:0.3em;"></pre>
|-
| style="border:none" | <pre style="display:inline;padding:0.1em;margin:0.3em;">three^^</pre>
|-
| style="border:none" | <pre style="display:inline;padding:0.1em;margin:0.3em;">four^|cuatro</pre>
|-
| style="border:none" | <pre style="display:inline;padding:0.1em;margin:0.3em;"></pre>
|}
|}

(Print the output list in any format you like, as long as it is it easy to see what the fields are.)
