should reduce time for feature generation

limit the number of operations done

Works on initial test cases

Division/multiplcation nodes cant have division features/inverse

empyt unit check

Check if this helps with memory problems

Did them one after another, adding both here now

SIS updated to use scores to check similarity and only send phi's that are needed

all lower rungs stored on processes, this was causing issues with set_value if not done this way

phi stored across all nodes not stored on all nodes

Initial commit towards resizing temporary storage arrays

Documentation added to feature space and base node operators

don't need to set things as often

check for cross correlation in the stored rungs

Features now point to a position in centeral arrays.

Recurisive solutions for all rungs above 2

Feature Creation, projection scores, and l0 normalization all parallelized

Refactored C++ SISSO code now running properly.

Further tests are needed to further debug, need to work on memory access and bringing in new features
