======Synopsis:======
$__jot__(<start> <stop> <interval>)

======Technical:======
   * If the <start> argument is omitted the empty string is returned.
   * If the <stop> argument is omitted the empty string is returned.
   * If the <interval> argument is omitted the default value of 1 is used.
   * If the <interval> argument is 0, the empty string is returned.
   * The <interval> argument should be an integer value -- support for fractional numbers will be added in the future.
   * The <interval> argument should be positive; but if you specify a negative value, the absolute value of <interval> will be used.
   * If <start> is less than <stop>, then consider the sequence \\ [<start>, <start>+<interval>, <start>+<interval>+<interval>, ...  <L>], where <L> is less than or equal to <stop>.
   * If <start> is greater than <stop>, then consider the sequence \\ [<start>, <start>-<interval>, <start>-<interval>-<interval>, ...  <L>], where <L> is greater than or equal to <stop>.
   * This function returns a list of words that correspond to the elements in the smallest sequence that models the appropriate sequence.

======Practical:======
This function creates a list of all of the numbers between <start> and <stop>,
with a step of <interval>.  Ranges can be ascending or descending, depending on
whether <stop> is greater than or less than <start>.  You can iterate over the
return value with [[FE]] or [[FOR]] i IN.  Another popular use is to pass the
return value to $[[chr]]() to create a range of ascii characters.

======Returns:======
Every <interval>th number between <start> and <stop>, inclusive.

======Examples:======
<file>
$jot(2 6)             returns "2 3 4 5 6"
$jot(2 7 2)           returns "2 4 6"
$jot(3 -2)            returns "3 2 1 0 -1 -2"
$jot(4)               returns ""  (empty string)
$jot(4 6 8)           returns "4"
$jot(a 4)             returns "0"
