Porting Rubi Integration rules to Symja

From the Rubi website:

Rubi is an extensive system of symbolic integration rules that can be systematically applied to determine the antiderivative of a wide variety of mathematical expressions. Organized as a decision tree based on the form of the integrand, the 6600+ rules Rubi uses can be viewed in human-readable form or downloaded in machine-readable form.

The Rubi converter programs are maintained in this project: github.com/axkr/Rubi-1.

The converter include 2 Java programs which generate Java files for the Symja package org.matheclipse.core.integrate.rubi

• the converter ConvertRubi.java for converting the Rubi integration rules /Rubi/RubiRules4.16.0_FullLHS.m into Java source codes IntRuleXXX (XXX counter for generated source files).
• the converter ConvertRubiUtilityFunctions.java for converting the Rubi utility function rules /Rubi/IntegrationUtilityFunctions.m into Java source codes UtilityFunctionsXXX (XXX counter for generated source files).

The generated rules for the package org.matheclipse.core.integrate.rubi are loaded in the static initializer part of the F.class.
