temp storage can be set manually

There were errors with temp_storage_reg and setting selected feature values

More feature elimination steps. Clear out register when doing generation/proejction

Did them one after another, adding both here now

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

Possible to resize based off of rung

Initial commit towards resizing temporary storage arrays

Removed _value_ptr and _feat_value_ptrs from OperatorNode
Allow set_value() and get_value_ptr() to accept offest and work directly on offset
value_ptr only thing to call set_value

Added type condition tests (initial simplification)
Added som more documenatation

Features now point to a position in centeral arrays.

Recurisive solutions for all rungs above 2

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
