Implement functions to encrypt and decrypt a message using the straddling checkerboard method. When setting the checkerboard up, it should take a 28 character alphabet (usually A-Z plus a full stop and an escape character) and two different numbers representing the blanks in the first row. The output will be a series of decimal digits.

Straddling checkerboard is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
