bc8c404449
This patch is the first step for sample integration. Actually the stick tables uses her own data type, and some converters must be called to convert sample type to stick-tables types. This patch removes the stick-table types and replace it by the sample types. This prevent: - Maintenance of two types of converters - reduce the code using the samples converters
