Version 2.1.0

Revert the breaking change(s):

• getComponent/addComponent/etc. now return a pointer (sorry). This may be changed back in the future, I mainly did this so I can make a wrapper pointer class (but we'll see if it's even necessary).

Version 2.0.0

BREAKING CHANGES:

• getComponent/addComponent/etc. now return a pointer (sorry). This may be changed back in the future, I mainly did this so I can make a wrapper pointer class (but we'll see if it's even necessary).
• Removed CRTP requirement for Components and Systems
• Supply list of component requirements/exclusions via variadic template (e.g. struct MySys : System<Requires<Foo, Bar>>; #20)
• Removed boost dependancy completely

Minor changes:

• Supply functors to World::createEntity

Misc:

• A boatload of more test cases
• Fixed animation bug(s) in examples
• Fixed collision example

There's probably some more I missed.

Version 1.1

Features:

• Added World::getEntities()
• Added World::clear()
• Added Movement example
• Added Collision example (thanks to johnmarinelli)

Bug Fixes

• Fixed Entity::Id's being re-cycled incorrectly.
• Fixed issue where re-activating Entities caused them to be re-added to their Systems.
• Added the ability for an empty Entity handle to check its validity without asserting.
• Removing Component caused crashes

Thank you jabza for helping to fix these bugs.
