DSS Sharp 0.11 based on DSS C-API 0.11.0

[PMeira]

DSS C-API version 0.10.4 should be released soon (few days max), and DSS C-API 0.11.0 should be released this month. This version should be compatible with the current DSS Sharp master.

Most open issues are on hold -- #4, #5, #6, #7 -- and waiting for DSS C-API 0.11.0, since there are API changes.
