Also changed the name of astMap to variableMap to better reflect what it's actually mapping to

Substituted with std::pair<bool, SymEngine::RCP<const SymEngine::Basic>> use instead

Mostly GPT generated test cases

Test case has been superseded by the newly added test suite to more robustly test for equation rearrangement

Previous system assumed that symengine expressions contained only 0-2 children, but in reality it could be any whole number. This adjusts the existing conversion logic to account for this.

Made it so that we also now consider mathml unary +/- operators

Can now handle unary plus, minus, unary minus, and CN types from AST (which means code now passes Analyser.rearrangeAdditiveEquations)

Had an error at equation 4

Also added brackets to equation comments to make things more clear

Now passes Analyser.rearrangeMultiplicativeEquations

Now covers a greater variety of cases

Symengine is not capable of rearranging trig functions into inverse trig functions (e.g. tan(x) = y cannot become x = atan(y))

Now has better Eq 1 test case and more consistent variable naming

Now supports
- Decimal point values (i.e. doubles)
- Constants (E, pi, and inf)

We need to ensure that there can only be one real solution for each

Some specific things had to be added to handle this
- CN representing integers must be appropriately converted since symengine requires exponentials to be whole numbers
- We need to filter out real from non-real solutions since we assume users will want to ignore the complex domain in most cases

Now assumes left child will always be the non-null component

They were making the code a bit faster but more difficult to maintain.

The idea is for the library type to be determined by CMake to allow building `test_utils` as static or shared, depending on the project's configuration.

It looks like now it's not enough to provide `CMAKE_PREFIX_PATH`?
