Translated to SMT-Lib by Maple SMTLIB package. 
* Simplified the original ProveInequality call for SMTLIB package

Application: Automated proof of (4.30) in 
D.S. Mitrinovic, Elementary Inequalities, P. Noordhoff ltd - Groningen, (1964)
("https://www.isinj.com/mt-usamo/Elementary%20Inequalities%20-%20Mitrinovic,%20et.%20al.%20(1964,%20Noordhoff).pdf")

All denominators in the original CAD call got cleared by introducing disjunctions with sign conditions:
a/b == c/d --> a d==b c && b<>0 && d<>0
a/b >= c  --> a >=b c && b >0  or ( a <= b c && b < 0)

Extra comment: The original Mitrinovic 4.30 call has an OR statement in the assert call. Here we split this into two files.
