ht_find() should return a bucket
Typo: typename of hash type
We must actually shift 1 instead of two, to compute 2^n
Added implementation for ht_find()
Fixup: Use division here, not modulo
Add ht.c to CMakeLists.txt
Fix: Includes in ht.h
[ci skip] This stuff gets annoying: Fixed the typename for the hash type
Added some documentation for the hashtable type
We store the power, 2 must be raised to, to get the size of the HT

This patch also adds a helper to get the bucket count of the HT.
Adapted: implementation of ht_init() for sizepower member
Adapted: Iteration in ht_destroy() for changed attribute "sizepower"
Fixed/Adapted: Bucket selection equaltion
