v1.7.9 (Thor Api Memory Optimizations)

Thor Api

• the From() function accepts pointers from now on.

• memory allocations reduced dramatically.

• huge performance improvement.

new way:

result := From(&items).Where(func(search ComplexObjectToSearch) bool {
		return search.Name == "Jane" && search.Flag == false
	}).Collect()
