Removes one recursive walk through the expression tree.

…holder function

Simplifies replace_placeholder_funcs function by removing a special case

Values needed for dimensional analysis are stored in the evaluation pass instead

Code generation still has issues

Use strings instead of BigInt for efficiency

Firefox is consistently timing out on this test

Still needs to be removed from JS code

rational exponents with large denominators causes very long calculation times.

Prevents losing exactness for symbolic results while speeding up numerical results

Add test for symbolic representation of small rationals

This allows functions like range that need to know the result of the calculation to set the correct dims. Range now works with inputs that have consistent units. New test added for this functionality.

Removed remaining unitless sub query code

Only impacted integrals with user functions in the integrand

Provides a significant speedup and eliminates any possibility of mismatch between passes for dim functions that need evaluation pass values

Needed since placeholder functions aren't used in this case and future versions of SymPy may change this behavior

Not needed with new single pass refactor
