Arithmos Maps: Hashmaps library and Map ADT

[pavly-gerges]

The following is a feature PR:

• Map ADT.
• Polynomial Hashing function using Horner's Rule with Cyclic-bit shifting operations.
• Hashing Compression function using Modular Arithmetics (i.e., Euclidean's Division Theorem).
• Hashmaps implementation with anti-collision system utilizing contiguous_buffers for memory reasons.
• Dynamic Runtime type-safety by associating enum values with the Map and the Element structures.
• Modification of the contiguous_buffers insert operations to be compatible with collisions and provide anti-collisions scheme.
• Hashing and Hashmaps techdemo demonstrating the various operations.

Gaps:

• Linked Buffers require a review and is not totally addressed with changes in this PR especially the collision schemes.
