define schemas as a hash, and validate hashes!

    require 'hashidator'

    schema  = {:name => String, :age => Integer}
    valid   = {:name => "Harry", :age => 20}
    invalid = {:name => 1234, :age => "twenty"}

    h = Hashidator.new(schema)
    h.validate(valid)   #=> true
    h.validate(invalid) #=> false

see examples/basic.rb for full coverage. it knows
classes, ranges, booleans, proc and duck typing. yay!
