Improved JavaDocs -- linked some Hash* classes to each other
Added files forgotten in da3bea7 (First building version) and bf5ab9c (Implemented floating keys/values/elements) commits. Yes, project was broken all the time. Sorry.
Fixed bug #16: free and removed values weren't ensured to be non-identical in impl.hash.CharHashFactory. Added tests for this.
Fixed bug in IncrementValueWithDefault, fixed CharShortMap.incrementValue JavaDoc comment
Added two missed Override annotations in HashCharSetFactory
#9: Adapted CharShortMap tests from Mahout Collections
