Server Puzzle release

• Added Server Puzzle model for server support
• Added SQLite data persistence for solvers with SQLite solver
• Added two more puzzles implemented by Mark Presten (Chairs and Triangle Peg Solitaire)
• Added/Removed more docs and tests

Refactoring Release

• Solver.solve() no longer takes in a required argument for a puzzle nor does it return the value of puzzle. This functionality has been placed into solver.getValue()
• Moved many files around for organization purposes.

v0.1.0: Merge pull request #11 from GamesCrafters/prod

• generateMoves for Puzzles using GeneralSolver now takes in a keyword argument "movetype". Details are in Puzzle.py
• PickleSolverWrapper is available for storing solvers into binary files, avoiding re-computation afterwards. Optional function getName allows you to set the name of the file itself.
• ALL filenames are required to have a lowercased first letter. All file names were changed to reflect this.
• The solver folder was renamed solvers
• Tutorials were reorganized and reeditted
• requirement.txt was added for dependencies
• test was renamed to add an underscore test_
• GraphPuzzle is available to create an actual Puzzle tree with nodes. Documentation is expected to come soon.
