`s`	A string starting with "ab_", followed by rational numbers a and b separated by "_". a and b must be integers or rational numbers of the form "int/int". See examples.

A list of the following elements:

`a_numer`	The numerator of `a`.
`a_denom`	The denominator of `a`.
`b_numer`	The numerator of `b`.
`b_denom`	The denominator of `b`.

parse_ab("ab_1_1") # gaussian: a = 1, b = 1
parse_ab("ab_2_5/4") # a = 2, b = 5/4
parse_ab("ab_5/4_3/2") # a = 5/4, b = 3/2
parse_ab("ab_3/2_0/0") # a = 3/2, b = 0/0 (log)
parse_ab("ab_1/2_0/0") # exp: a = 1/2, b = 0/0 (log)
