fallback solutions
* if everything fails,
    set got dir path to abbsolute value and edit work tree in place
* if comsumption fails,
    due to modulefolder exsisting, revert move and trye to use exsisting folder instead,
    if this ressults in error, re revert to initial
	move inplace module to x prefixed
	atempt to consume again
* if no module is provided, utelyse everything to find possible folders
    use hamming distance like priorit order
	where
	1. exact parrentmatch
	   rekative to root
	    order resukts by total exact


	take first precedance
	2. predefined patterns taken
	and finaly sort rest by hamming
