v1.3

Version 1.3 - Fourth release on CRAN

BUG FIXES:

• Ensure that 'description' returns a 'type' column if there are 0 rows and include_synonyms = TRUE
• Ensure that 'description' returns only one Fully Specified Name per concept, and 'semanticType' returns only a single result per concept

NEW FEATURES:

• New function 'createTransitive' to generate a transitive closure table containing all ancestor-descendant pairs. This makes
  subsequent ancestor / descendant searches quicker
• Revised ancestor and descendant functions to be able to use a transitive closure table
• New function 'addInactiveConcepts' to add inactive concepts to codelists, using the history and query tables
• New functions 'createCDB' and 'createMiADECDB' to generate a concept database and lookups for named entity recognition
• New function 'createDisambiguationTrainer' to use longer SNOMED CT terms to create texts to help train disambiguation of short terms.
• New functions 'decompose', 'batchDecompose' and 'createComposeLookup' to create a lookup table for composition of SNOMED CT concepts
• New function 'compose' to select a detailed SNOMED CT concept based on a general concept and separate concepts for attributes such as body site
