* Created new SerialBufferBase as a parent of SerializeBufferBase. Renaming interface functions to be less confusing. * Deprecating copyRawOffset. No direct use-cases in F' core. * Make SerialBufferBase a true pure virtual interface. * Changing Serializable to work with SerialBufferBase parent interface. * Changing copyRaw and copyRawOffset to work with SerialBufferBase * Updating documentation for SerialBufferBase usage * Adding some documentation. Adding missing ASSERT in copyRaw. Fixing some bugs that new ASSERT uncovered. * Renaming SerializeBufferBase to LinearBufferBase. Add a using declaration to maintain backwards compatability. Properly mark LinearBufferBase functions as override. * Filling in the rest of the docstrings for the classes in Serializable * Removing redundant virtual keyword on override function * Applying clang formatting * Incorporating PR comments * Fix compile issues * Bump version to alpha * Format * v --------- Co-authored-by: M Starch <LeStarch@googlemail.com>
