test_run displays errors with file and line number.
CTRL-C throws an error.
some warnings detected by LGTM or VS fixed.
allows .m file empty to be called.
macros in memory reworked to support also MEX.
C MEX compatibility, load and build fully compatible with other softwares.
inmem builtin returns names of functions, MEX-files in memory.
mexext builtin returns binary MEX file-name extension.
main function in .m no more require to be the first in file.
checks in the .m function that other local function names are not duplicated.
.m timestamp checked if addpath(...,'-frozen') is not enabled.

struct behavior with function_handle.

nargin, nargout behavior with mex updated.
BREAKING CHANGE:
function ... endfunction and function ... end are equivalent (increase compatibility ;).
file extension .m is managed by Nelson.
About compatibility: scripts and functions developed with Nelson should work with other tools managing .m files. The reciprocal is not necessarily true.
.m is default and alone file extension.
