function dummy=savebasevector(vec,fname,varargin)
%SAVEBASEVECTOR Stores vector in LHOTSE BaseVector format
% SAVEBASEVECTOR(VEC,FNAME,{TRUETYPE=6},{NOTAG=0}) stores vector
%   VEC into file with name FNAME, using LHOTSE BaseVector file format.
%   FNAME can also be a file identifier (as returned by FOPEN) for a
%   file opened in big-endian byte order. In this case, the file is
%   not closed after writing. If TRUETYPE is given, VEC is converted
%   into the following type before writing:
%   - 1: schar (signed char)
%   - 2: uchar (unsigned char)
%   - 3: int32
%   - 4: uint32
%   - 5: float32
%   - 6: double [default]
%   - 7: uint8 (this is bool in LHOTSE)
%   If NOTAG~=0, we do not write a file tag.
%
%   NOTE: The format of LHOTSE StVector is the same as
%   BaseVector<double>.
