delta handling is broken for composite types

[nvdk]

I guess the current implementation is supposed to just ignore composite types, but it doesn't even do that due to a typo in

mu-search/lib/mu_search/delta_handler.rb

Line 197 in 42277fe

type_definitions.reject{ |type, config| config.has_key?("composite_tyes")}.each do |type, config|

and

mu-search/lib/mu_search/delta_handler.rb

Line 210 in 42277fe

type_definitions.reject{ |type, config| config.has_key?("composite_tyes")}.each do |type, config|

[nvdk]

this is fixed in #38
