"-pad" will insert zeroes in front of numbers with fewer digits than the "-to"
value.

Examples:
[pk_range: 1, 10] -> 
	array: (1), (2), (3), (4), (5), (6), (7), (8), (9), (10)

[pk_range: -from=8, -to=24, -by=4, -prefix='my_', -suffix='_test', -pad] ->
	 array: (my_08_test), (my_12_test), (my_16_test), (my_20_test), (my_24_test)

To Do:
Allow for an "-Alpha" parameters which should return alphabetical ranges, such
as "aaa, aba, aca" etc.
