feat: implement IsModSimplifiable in Integer class

[ohhmm]

No description provided.

[devin-ai-integration]

The method getExponentiation() has been renamed to eexp() throughout most of the codebase, but this line still uses the old name. Please update to use e.eexp().

[devin-ai-integration]

The method getBase() has been renamed to ebase() throughout most of the codebase, but this line still uses the old name. Please update to use e.ebase().

General PR Feedback:

1. PR Title/Content Mismatch
   The PR title suggests implementing IsModSimplifiable in the Integer class, but the changes primarily focus on renaming getBase()/getExponentiation() to ebase()/eexp(). Please update the PR title to reflect the actual changes (e.g., "refactor: rename getBase/getExponentiation methods to ebase/eexp").

2. Build Failures
   While most of the codebase has been updated to use the new method names, there are still instances using the old names (see inline comments). These are causing build failures across multiple platforms.

3. API Changes
   Since this is an API change:

• Please add a note in the PR description about the method renaming and its rationale
• Consider documenting this change in the changelog if one exists
• Ensure all tests are updated to use the new method names

PR Title/Content Mismatch

The PR title suggests implementing IsModSimplifiable in the Integer class, but the changes primarily focus on renaming getBase()/getExponentiation() methods to ebase()/eexp(). Please update the PR title to reflect the actual changes (e.g., "refactor: rename getBase/getExponentiation methods to ebase/eexp and implement IsModSimplifiable").

Method Naming Inconsistencies

Several instances of getBase() and getExponentiation() remain in the codebase and need to be renamed to ebase() and eexp() respectively. For example, in Exponentiation.cpp line 52, you have return getMaxVaExp(getBase(), getExponentiation()); which should be return getMaxVaExp(ebase(), eexp());.

Here are more instances that need to be updated:

• In Exponentiation.cpp, line 52
• In Exponentiation.cpp, lines 492, 496, 528, 537, 542, 564, and many others
• In Fraction.cpp, lines 248, 250, 254, 338
• In Logarithm.cpp, lines 67, 69, 70, 77, 84, and others

These inconsistencies are causing build failures because some parts of the code are using the new method names while others are using the old ones.

Implementation Notes for IsModSimplifiable

1. The implementation in Integer.cpp looks correct and the tests in Integer_test.cpp cover various scenarios.

2. However, the test comments in Integer_test.cpp line 474 states "Test with variable (should defer to variable's implementation)" but the test checks that the result is not simplifiable. Consider updating the comment to "Test with variable (should not be simplifiable)" to match the actual test behavior.

3. Similarly, the comment on line 479 says "should not be simplifiable directly" which is more accurate. Consider making these comments consistent.

Recommended Verification Steps

Since the PR contains both method renaming and implementation of IsModSimplifiable, it's important to verify that:

1. Build the codebase locally to verify there are no compilation errors, especially checking for any remaining instances of getBase()/getExponentiation() that weren't renamed to ebase()/eexp()

2. Run the tests with a focus on Integer_test.cpp to verify the IsModSimplifiable functionality works as expected:

   cd ~/repos/openmind
   # Build the project
   mkdir -p build && cd build
   cmake ..
   make
   
   # Run the Integer tests
   ./omnn/math/test/Integer_test
   

These verification steps will help ensure that all method renaming is consistent and that the IsModSimplifiable implementation works correctly.
