Added logic AND to the pattern grammar and parser, updated corresponding unit tests and code in rete network and sparkwave
Added temporal operator BEFORE(int,int) to sparkwave pattern grammar
Added temporal operator BEFORE(int,int) to sparkwave parser and unit tests
Added the parameters EPSILON_ONTOLOGY and STATIC_INSTANCES to parser/lexer and unit tests.
SparkwaveNetwork doesn't take anymore the parameters epsilonOntology and staticInstances, instead those parameters are specified in the pattern file
Restructured SparkwaveNetwork and introduced SparkwaveKernel for bootstrapping all needed threads. Is capable to create for each pattern a Rete Network including alhpa,beta and epsilon. Server and parser-thread are feeding using queues the triples to the corresponding SparkwaveProcessors
Improved:Pattern toString output; Added:Sparkwave accepts more than one pattern
Fixed: unit tests FileHandler and InfoObjectSubmission
Updated: spark pattern grammar, epsilonOntolgy and staticInstances is optional
Fixed: unit test for IndexStructure took too long to finish
Improved error output for Sparkwave start
Refactoring of variable names in spark-wave project; Added TODOs
