working time interval type
some code cleanup and renaming
Abstraction and type integration

abstracted classes
implemented Long and Date intervals
commented code
wrote new test cases

there is a BUG! if you have an interval 15-25 and you look for 17-20, it will not be found
simplification

NumericIntervalType is no longer abstract and does not need to be extended
fixed query bug (not matching inner interval)
fixed output bug
introduced separator parameter to schema
all tests pass
finished

fixed last issues
added valueSource for NumericIntervalType
renamed testing resources to solr-intervals
integrated NumericIntervalType code into won-matcher-solr project
solr unit tests now run using RAMdirectoryManager

the index is no longer stored to the disk
Merge branch 'origin/master'
fixed package names, added ram directory anager to second unit test, all tests passing
NumericIntervalType integration

added the interval type to the project
adapted builder for it
added a test to NeedModelBuilderTests that FAILS!! TODO
added comos lang3 as a dependency because it is used by the NeedBuilderBase
adapted SolrFields to reflect interval changes and adapted all cascading classes
changed price field type from double to float
Fixed some bugs in builder

extracted Interval class to avoid generics errors
fixed interval flip from to bug
fixed double date field type bug
fixed test file to contain only needed fields
removed solr-intervals project used for developing field type
Finish time-indexing
