ururu v1.0.1

ururu

No URURU, just LRU

Yet another LRU cache implementation. But why? Yeah, there are a few reasons for that:

1. Simplicity in implementation means better maintainability.
2. Simplicity in interface means better learnability (see "ISO/IEC 9126 Software engineering — Product quality").
3. Zero dependencies means more predictability, safety and reduces overall application size.
